Discrete source S₁ has 4 equiprobable symbols while discrete source S₂ has 16 equiprobable symbols. When the entropy of these two sources is compared, the entropy of:

In an AM system receiver. the mixer translates the carrier frequency f_c to a fixed intermediate frequency of 450 kHz. Given a broadcast signal of frequency 900 kHz. What is the corresponding image frequency when a superhetrodyne receiver is employed with local oscillator frequency greater than the broadcast signal frequency?

A binary ripple counter is required to count up to (16,383)₁₀. If the clock frequency is 8.192 MHz, the number of flip flops required, and the frequency at the output of the MSB is:

Consider the following sum of products expression, F

The equivalent product of sums expression is

The residue of z cos (1/z) at z = 0 is

The Bode plot of a system is shown below. The transfer function of the system is:

The following circuit will work as which type of Filter ?

In the bipolar current source of the below circuit, the diode voltage and transistor BE voltage are equal. If base current is neglected then collector current is, given the transistor is of NPN type
