A CB amplifier is operating with RL = 10kΩ, Rc = 10kΩ, and Rsig =100Ω. At what current Ic should the transistor be biased for the input resistance Rin to equal that of the signal source? What is the resulting overall voltage gain? Assume α ≈ 1
Use a chain of flip-flop to implement a shifter register
The voltage drops across three resistors in series are measured to be 10.0V, 15.0V, and 25.0V. If the largest resistor is 47.0 ?, what is the value of the smallest resistor?
A digital communication system employs differentially encoded BPSK modulation scheme with non-coherent (differential) reception. If the Eb/N0 is 8 dB, what is the probability of bit error for the system
A magnetic pickup coil is being used to make measurements which areproportional to the time derivative of the magnetic flux density, dB/dt. You wishto integrate this signal to get the magnetic flux density, B.
The unit step response of a linear time invariant system is s(t) = (1 - e-at)u(t). Where "a" is a positive, real valued constant. What is the impulse response of the system. What is the frequency response of the system.
What is the maximum symbol rate which can be sent over this link? If a binary line code is used, what is the maximum bit rate? What is the maximum bit rate with 4-ASK symbols?
In a swamped common-emitter BJT amplifier, as shown below, if Vcc = 12 V, R1 = 8.2 k , R2 = 10 k , Rc = 500 , RE = 1 k , VBE = 0.7 V, and = 100, what is the transistor's emitter current
An op-amp has an open-loop gain of 200 V/V. If this op-amp is used to build an inverting amplifier with an absolute gain of 50V/V: (a) What must the smaller resistor be adjusted to, if the larger resistor is 100 k
If she is a carrier, then each prince has a 50-50 chance of having hemophilia, independently of the other princes. If the queen is not a carrier, the prince will not have the disease. Suppose the queen has had three princes, each without the disea..
an electric kettle is required to heat 0.6 litre of water from 10 degrees celcius to boiling point in 5 minutes,the supply voltage being 240 volts. The efficiency of the kettle is 87%. Assume the specific heat capacity of water to be 4190J/kg.K
