Question

The full-power bandwidth, fM, is the maximum frequency at which

(a) an output sinusoid with an amplitude equal to the op-amp rated output voltage (Vo max) can be produced without distortion

(b) it is the range of the frequencies in which the amplitude of output signal is equal to or greater than half of the op-amp rated output voltage

(c) it is the range of the frequencies in which the amplitude of output signal is equal to or less than half of the op-amp rated output voltage

(d) It is the range of the frequencies in which the power gain is half or more than half of the maximum rated power gain of the op-amp

I had been asked this question in a national level competition.

Question is from Large Signal Operations on operational Amplifiers in section Operational Amplifiers of Electronic Devices & Circuits

Answer 1

Right choice is (a) an output sinusoid with an amplitude equal to the op-amp rated output voltage (Vo max) can be produced without distortion

The explanation is: This is the only statement that satisfies the definition of the full-power bandwidth.
