1. Design four (4) different 5 volt DC power supplies to operate from 230 volts AC.
Explain the strength and weaknesses of each of the designs and why some design work better than others.
2. Calculate the appropriate values including nominal value, power rating & voltage rating etc. for each of the components, in each of the designs. Explain why you have chosen that type and/or value.
3. Use "MultiSim" to simulate each of the 4 circuits. Include in your report a snap shot of the waveforms after each stage in the circuit (from the input to the output) explaining the characteristics of and reason for each waveform shape.
4. Use "MultiSim" to generate each of the schematic diagrams, and the input and the output waveforms of each circuit.
Q. A current i(t) = 20 cos(2π × 60)t A flows through a wire. Find the charge flowing, and the number of electrons per second that are passing some point in the wire.
Q. Write a short note on heat sink For transistors handling small signals ,the power dissipated at the collector is small.Such transistors have little chances of thermal runawa
For Parity Flag PRE ( Return on Parity Even) and RPO ( Return on Parity Odd) Instructions RPE returns from the subroutine to the calling program if parity flag is not s
Explain Medium length lines? Medium length lines cover lines in the range of 50 to 150 miles (80 to 240 km). Due to the increased length of the line, the shunt capacitance of t
Using the audiorecorder() function in MATLAB, make a recording of your voice. Use a sample rate of 8kHz, 16 bits per sample, and aim to record around 2 seconds worth. Quantize the
What is the effect of overheating on the life of an electric insulator? An insulator is designed to withstand amount of heat. However, when an insulator is overheated so dielec
Q. (a) An ampli?er with F 0 = 3 or 4.77 dB, f 0 = 4 GHz, and BN = 14 MHz is used with an antenna forwhich T a =200K. The connecting path loss is 1.45, or 1.61 dB at a physical t
