Butterworth Filter Circuit Diagram for Voice Signal Applications Recovery

Butterworth Filter Circuit Diagram for Voice Signal Applications Recovery -A unity gain multipole Butterworth filter circuit diagram with ripple less

Butterworth Filter Circuit Diagram for Voice Signal Applications Recovery -A unity gain multipole Butterworth filter circuit diagram with ripple less than 0.15dB in the human voice band is shown in the following picture.

By using CMOS op amps, a voice signal recovery applications (radios, cellular phones, and voice pagers) can be properly recovered using a low power bandpass filter implementation matched to the voice spectrum.

The circuit uses TC1029 dual CMOS operational amplifier for low power applications such power management circuit or battery operated equipment.
