The voltage gain of a tuned amplifier is ___________ at resonant frequency
Assertion: The process of testing the frequency response of amplifier and filter can be done by sweep frequency generator that automatically varies its frequency over a pre-determined range. Reason: The sweep frequency generator should have a ramp generator which applies a linear ramp voltage the input of a voltage tuned oscillator (VTO).
