In order to increase the bandwidth of tuned amplifiers, one can use: 1. Tuned circuit with inductance having high Q factor 2. Double tuned amplifier with two tuned circuits coupled by mutual inductance 3. Staggered tuned amplifiers in which different tuned circuits which are cascaded are tuned to slightly different frequencies
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).
