WebSep 29, 2011 · Low-Frequency Amplifier Response – Voltage gain roll-off at low frequency The decrease in voltage gain with frequency is called roll-off. Let’s take a frequency that is one-tenth of the critical frequency (f =0.1fc). Since Xc1 = Rin at fc, then Xc1 = 10 Rin at 0.1fc because of the inverse relationship of XC1 and fc. WebThe critical frequency is found to be approximately equal to 0.17, both for Re = 80 and for Re = 90 and about 0.18 for Re = 100, although this is a very crude approximation for the reasons mentioned above. As the critical value of Gr for these values of Re is approached, the oscillations are of very low amplitude and the time required for the steady-periodic …
