WebThe low-frequency response of this amplifier is determined in part by these three capacitors (C i, C o and C E). The result is essentially a combination of three high-pass filter networks that allow signals having frequencies greater than the cutoff frequency of the dominant network to pass through while attenuating all others. WebOn the left-hand part, a simple non-inverting adder adds a base signal (5V, 1kHz) and an artificial low-voltage high-frequency noise (500mV, 100kHz). On the right-hand side of the schematic, the low-pass filter filters the signal. The gain is equal to -R2/R1. The cutoff frequency is defined by f=1/ (2*pi*R2*C2).
