Abstract:
In the experiment AC Circuits. Oscilloscope, the main objective was to use a signal generator (SG) to create a sine wae and using an oscilloscope we had to bserve the various components of a sine waves and there relationships; the component RMS, amplitude, period and frequency. Another objective was to use the RLC circuit to determine the resonant frequency. In order to complete these ojectives the circuit was first set up as in figure 1 and RMS, period, frequency and amplitude were calculated and measured. The experimental amplitude was 0.875Vac, the frequency was 1001Hz, and the period was one second. The difference beween the theoretical frequcy from the signal generator was compared to the experimental frequency giving a 0.1% error. For the second part of the lab the RLC circuit was set up (figure 2) and from there the resonant frequency was found for this was done three times (table 1). After this the voltage drop was measured in the range of 800-300Hz; the different frequencies withc corresponding average power that dissipated in the resistor was inputted into GA (table 2,). From there the power vs frequency graph was plotted. and finally the theoretical angular frequency 1.0846 x 104rad/sec was compared to the experimentally found frequency of 1.0820 x 104rad/sec, giving a 0.24% error.

Objective:
In experiment number nine “AC Circuits. Oscilloscope” The main objective in the experiment was to use a signal generator to produce an AC signal and determine the relationship between the rms value and the amplitude of the voltage of the wave and also the period and the frequency of the signal. A secondary objective was to use an RLC circuit and determine both the resonant frequency and the dissipated power of the main resistor.…...

...E663 Laboratory session 8: AC Operational Amplifiers Agrim Ganti University College London 5th December 2008 ABSTRACT The report is written on an investigation which comprises of testing three operational amplifier circuits with AC signals. The three types of circuit include the integrator, the AC inverting amplifier and the AC non-inverting amplifier circuit. The integrator circuit was tested with a square-wave and a sinusoidal wave input signal at 1kHz frequency. The results showed that the square-wave input signal produced a triangular wave output whereas the sinusoidal input produced a sinusoidal output signal with a positive 90 degree phase shift. Both output signals were showed to be the integral of their relative input signals. The output voltage gain of the AC inverting and the AC non-inverting amplifier circuits were tested with a frequency range of 100Hz to 10kHz. The results were plotted on a logarithmic scaled graph which showed that both amplifiers acted like high-pass filters, each amplifier achieving its maximum gain set by the specification at higher frequencies nearer to 10kHz. The only difference between the two op-amps was that the AC inverting amplifier achieved negative gain in comparison to the positive gain achieved by the AC non-inverting amplifier. For further investigation, the frequency was increased above 10kHz for the AC inverting amplifier circuit which showed a linear fall in gain, which was explained by the theory of slew rate......

...klzxcvbnmqwertyuiopasdfghjklzxcvbnm Circuit City: Rejection PaperSimplicity Guaranteed4/11/2012 By: Da’Terryon Sturghill | What was Circuit City? Circuit City Stores, Inc. was an American vendor in brand-name buyer electronics, individual computers, entertainment software, and until early in 2000 came accompanied with large appliances.  I mean Circuit City was an overconfident brand that America had grown to depend on through the years to offer many products which facilitate people to take pleasure in their lives. I have researched and found that the history of Circuit City is amazingly dating back to 1949. CircuitCity.com had been developed all-new and geared up to provide the customers with a wider range of products than previously offered in Circuit City stores or online in order to remain current with the continuously growth in technology as well as competition. Here is what I found of the projected items sold at the Circuit City establishment an extended variety of customer electronics, desktops, notebooks, net books, HDTVs, DVD and Blu-Ray players, DVRs, Home Theater Systems, GPS Players, Digital Cameras, Hi-Def Camcorders, Digital Picture Frames and so much more. Plus, provided a greatly expanded selection of computer mechanism, like computer cases, motherboards, memory and processors – all the things to promote your existing system, or build your own.

Circuit City

...Circuit City Circuit City The Circuit City story began in 1949 when entrepreneur Sam Wurtzel opened a small store in Richmond, VA, after he learned that the south’s first television station was going on the air. Over the next 20 years, Sam grew his company into a 100 store chain. His son, Alan became CEO in 1972 and created the ground-breaking superstore format that evolved into Circuit City. When Alan retired from the board in 2000, Circuit City was a fortune 500 company with more than 600 stores and 60,000 employees. Circuit City was a shining example of exceptional management practices in a 2001 best- selling book “Good to Great.” However, cracks were beginning to show in the company’s foundation. Circuit City’s rise and fall revealed leadership lessons and emphasizes the critical strategic role that training and development play in a company’s continued success. For its first 50 years, Circuit City (originally called Wards TV) was a pioneer in the rapidly changing consumer electronics industry. The following are what made the company great. Things that made the company great THE FIRST BIG BOX SUPERSTORE In 1975, Alan Wurtzel transformed the retail landscape in America by creating the first big-box superstore with a focus on Savings, Selection, Service, and Satisfaction. His “4 S’s” were captured in policies and processes that were easily understood by the customer and easily executed by his employees. Circuit City offered a low price guarantee, a 30 day......

Integrative Circuits

...The integrated circuit was invented in 1958 and 1959 by Jack Kilby and Robert Noyce. Before the integrated circuit was created, computers used single transistors and before transistors vacuum tubes were used. However, vacuum tubes were inefficient as they gave off so much heat and used enormous amounts of energy which is why the invention of transistors, which used semiconductors, was a breakthrough in the technology. Transistors are used on integrated circuits and scientists have been able to increase the amount that can fit on a circuit in record numbers. Gordon Moore, a cofounder of Intel, noticed a trend of the capacity of each new chip that was created compared to its predecessor. He found that the size nearly doubled every two years and this still holds true for today. Below is a graph showing the transistor count vs. the year the transistor was introduced and we can see that every year the count increases in a linear fashion. This is actually amazing because not only is the count of transistors increasing the chips themselves are decreasing in size. This is the result of new materials being used such as silicon and graphene. The amount of transistors that can fit on a single chip is somewhere between 2.5 billion to 3 billion, however if Moore’s law continues to hold true, which history shows that it has, this number is expected to increase in years to come. The progression of technology is really incredible as computers have gone from the size of a large...

Pepcid Ac

...Q. How should Pepcid be positioned- treatment or prevention- and what are the implications? Pepcid Ac would work best when positoned as a treatment drug.We can look at it from different levels: Market demand/ Market research- - 2 tests with BASES methodology indicate that treatment has greater appeal over prevention with respect to the target groups- dual users as well as traditional antacid users. (Table D). While the focus groups and concept tests favored prevention and treatment (both together). However, JJ’s extensive experience with this BASES technique makes the findings more reliable. JJIM”s core competency- Merck’s strength is is R&D’s expertise. The treatment positioning focuses on the product’s benefits.It outperforms the existing antacids in the OTC market.However the medication’ s ability to prevent is questionable. The treatment strategy will also rely on JJ’s core competency is its consumer marketing and sales. In the recent past (1990 t0 1993) JJ successfullyswitched from prescription to OTC medications , twice. For instance,JJ drove Immonium sales from 31.5 million in 1987 $ to 125 million in 5 years. (table b) FDA as a collaborator- FDA’s rjected JJM’s to sell Pepcic AC on the grounds that the clinical trails failed to show its perforamnce as prevention medication.If JJM drops this claim it has a higher chance to be approved to be the first – to – market. Also, it is more advantageous for it to be the first-entrant to the OTC switch......
