Pass-band filter

00:34:06

A pass-band filter is a system keep only a certain frequency group and reject the other.

This system is composed of three parts:
    - a signal generator to make a signal composed of different frequency and different waveforms
    - the pass-band filter
    - a signal processing part to make a "clean" square signal

The first operational amplifier is used to increase signal voltage. The second is used to make the square signal

The output signal is a square signal with a frequency of 10kHz
