Problem 57-5
Source: Problem prepared by the author of the site.
Assume an amplifier with a midband gain of Avm = 400 and with a frequency response given by
f1 = 40 Hz and f2 = 16,000 Hz. Calculate the gain of this amplifier in the
frequencies of 20 Hz and 20,000 Hz.
Solution of the Problem 57-5
As we know the midband gain and amplifier cutoff frequencies, so using the equations
eq. 57-06 and eq. 57-07 found the solution to the problem. Thus, for the frequency of 20 Hz, we have:
E para a frequência de 20,000 Hz, temos:
