Capacitor fourth-order low-pass filter circuit diagram
Capacitor fourth-order low-pass filter circuit is shown as below. The circuit uses an LM348 op amp four high-level low-pass filter circuit. For example, fc = 20KHz, filter transmission coefficient is Ho = 1, Q01 = 0.514, Q02 = 1.306. Because the count of band-pass amplification factor is the same with the four amplifiers. So it is enough to equip with a current source (LM334Z). You can have a precise adjustment by potentiometer RP.
