List of top Analog Electronics Questions

Given below are two statements, one is labelled as Assertion (A) and the other is labelled as Reason (R):
Assertion (A): Emitter-follower configuration of BJT is used for impedance- matching applications.
Reason (R) : In a common-collector configuration of BJT, the output voltage at the emitter is in phase with input signal. 
In the light of the above statements, choose the correct answer from the options given below.
A superheterodyne receiver to operate in the frequency range 550 kHz to 1500 kHz and the IF is 455 kHz. What is the possible tuning range of local oscillator frequency?
The characteristics of an ideal op-amp are (where BW = Bandwidth, SR = Slew Rate)
