Question 1 of 5

An amplifier has an open loop gain of 100 and lower and upper cut-off frequencies are 100Hz and 100kHz respectively. A feedback network with a feedback factor of 0.99 is connected to an amplifier. The lower and upper cut-off frequencies are-

A

f_{L}=1 \mathrm{~Hz}, \mathrm{f}_{H}=100 \mathrm{kHz}

B

f_L=1 \mathrm{~Hz}, \mathrm{f}_H=10 \mathrm{MHz}

C

None of the above

D

f_{L}=1 \mathrm{~kHz}, \mathrm{f}_{H}=100 \mathrm{MHz}
