Engineering

Consider the two feedback networks shown in Figures (a) and (b).

The 3 dB frequency of the amplifier A₁ is 100 Hz and the 3 dB frequency of the second amplifier A₂ is very large. The feedback transfer functions are β₁ = 0.1126 and β₂ = 0.0245.

(a) Determine the 3 dB frequency of each closed-loop network.

(b) What conclusion can be made as to the "better" closed-loop system?
