What is the total voltage gain of a high frequency response of multistage amplifier if the gain of first stage is 14dB, gain of the second stage is 12dB and gain of third stage is 24dB?

(a) 40dB

(b) 50.32dB

(c) 50dB

(d) 40.32dB

I have been asked this question in a job interview.

The origin of the question is High Frequency Response of Multistage Amplifiers in portion Frequency Response of Electronic Devices & Circuits

The correct option is (c) 50dB

The best I can explain: The total gain of a high frequency response of multistage amplifier is the sum of the multiple stages when the gain is calculated is decibels. Given, AV1 = 14dB, AV2 = 12dB and AV3 = 24dB

AV = AV1 + AV2 + AV3 = 14dB + 12dB + 24dB = 50dB.
