Universal Active Filter circuit
Universal Active Filter circuit is shown below. Referring to the circuit as shown, its center frequency f0 = 3.4kHz, notch frequency fc = 9.5kHz and quality factor Q = 3.4. Transfer coefficient is 0.1for the high-frequency filter and is 1 for the band pass filter or the low-frequency filter. And 10.f0Q ≤ 200kHz is for the notch filter. When the output sinusoidal signal is with 10V, its highest frequency is not more than 200kHz.
