A circuit is said to be selective if it has a _____ peak and ____ bandwidth.
A. Blunt, narrow
B. Sharp, narrow
C. Sharp, broad
D. Blunt, broad
The question was asked in an online interview.
This interesting question is from Selectivity topic in portion Resonance in AC Circuits of Basic Electrical Engineering
Correct choice is B. Sharp, narrow
For explanation: For a circuit to be selective, it should have high quality factor. And we know that for high quality factor, resonance frequency should be high(peak should be sharp) and bandwidth should be narrow.
