Consider a voltage amplifier having a frequency response of the low-pass STC type with a dc gain of 60 dB and a 3-dB frequency of 1000 Hz. Then the gain db at

(a) f = 10 Hz is 55 db

(b) f = 10 kHz is 45 db

(c) f = 100 kHz is 25 db

(d) f =  1Mhz is 0 db

I have been asked this question in an internship interview.

My question is based upon Frequency Response of Amplifier in portion Signals and Amplifiers of Electronic Devices & Circuits

Best answer
The correct answer is (d) f =  1Mhz is 0 db

The best I can explain: Use standard formulas for frequency response and voltage gain.
