Question 1

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

Accepted Answer

f = 1Mhz is 0 db

Answer

f = 10 Hz is 55 db

Answer

f = 10 kHz is 45 db

Answer

f = 100 kHz is 25 db

Question 2

STC networks can be classified into two categories: low-pass (LP) and high-pass (HP). Then which of the following is true?

Accepted Answer

LP network passes dc and low frequencies and attenuate high frequency and opposite for HP network

Answer

HP network passes dc and low frequencies and attenuate high frequency and opposite for LP network

Answer

HP network passes dc and high frequencies and attenuate low frequency and opposite for LP network

Answer

LP network passes low frequencies only and attenuate high frequency and opposite for HP network
