Consider an open loop circuit with lower cutoff frequency 5kHz and upper cutoff frequency 20kHz. If negative feedback is applied to the same, choose correct option stating the new cutoff frequencies.

Consider an open loop circuit with lower cutoff frequency 5kHz and upper cutoff frequency 20kHz. If negative feedback is applied to the same, choose correct option stating the new cutoff frequencies. Correct Answer Lower cutoff = 2kHz, Upper cutoff = 25kHz

Negative feedback decreases lower cutoff frequencies and increases the higher cutoff frequency. fHF = fH(1+Aβ) fLF = fL/(1+Aβ) Total bandwidth is thus increased.
