For the network of given figure:
a. Determine the current I.
b. Find V.
Design a circuit that will indicate the birth months of February, April and May. The month is specified by a 4-bit input, A3:0. For example, if the input bits are 0001, the month is January and if the inputs are 1100, the month is December.
a). Determine the power this amplifier will deliver to a 4 ohm load, to an 8-ohm load, and to a 1K-ohm load b). What would be the open-circuitvoltage of the amplifier if the signal level were increased
A sequential circuit receives decimal numbers encoded in BCD one digit (4 bits) at a time, starting with the least significant digit. The circuit outputs are the 10's complement of the input number, also encoded in BCD least significant digit first.
For a modulating signal) x(t)= (t/T) a) Write an expression for the PM modulated signal. b) Write an expression for the FM modulated signal. c) What is the maximum phase deviation of the PM signal
A production plant needs a counter that will count 4,000 items before resetting and recycling. How many flip-flop stages would this counter require
Why is it that a photoconductive detector gives a current gain while a photo emissive detector does not? What are the disadvantages of photoconductive detectors? Under what circumstances would you use one?
Calculate the carrier concentrations and the type of semiconductor if a pure silicon crystal at 300K is doped with 2.5×10^13 cm-3 boron atoms.
QI The circuit diagram of an active linear filter is shown in Figure Ql. (a) Derive an expression for the transfer filmiest of the filter. (b) Hence find an expression for the frequency response of the filter.
Derive a minimum-cost realization of the four-variable function that is equal to 1 if exactly two or exactly three of its variables are equal to 1; otherwise it is equal to 0!
The instantaneous power p into a one port containing resistors and inductors has maximum value 100(1+sqrt2) W and minimum value 100(1-sqrt2)W. (note that instantaneous power is measured in W, and it contains various contributions
Explanation of the circuit: Two opamps on the top are the buffer amplifiers before and after sampler. Sampler is a JFET used as analog switch; its gate is driven by the narrow pulse train as specified above. There are two identical active lowpass ..
An AC signal has a peak value of 100 V and a frequency of 60 Hz. If the voltage crosses zero in a rising direction at t=0 seconds, what is the instantaneous voltage at t = 0.004167
