Posted by Graham Lambert | DIY Electronics | 0 . If you have ever used a tone control on a radio, stereo, or guitar, you have used an audio filter. An audio filter is a circuit that has been designed to let certain audio frequencies pass in …
Passive Filter Circuits : 4 Steps - Instructables
https://www.instructables.com/Passive-Filter-Circuits/
A bandstop filter is a circuit that ideally filters out signals with frequencies in a certain range. This range can be quite large, depending on inherent characteristics of the circuit. The smaller the range of frequencies the circuit filters, the higher the Q factor it is said to have.

The circuits will be active filters using an operational amplifier (op-amps). The gain for each frequency band will be regulated using variable resistors, connected at the filter circuits’ input. The different frequency components will be combined at the filters’ output stage and connected to an LM386-based power amplifier circuit. The amplifier circuit will boost the combined audio …

Simple audio noise filter circuit for stereo system. In the receiver, stereo radio station. Usually, have more noise than listening in mono. Because the stereo system is split signal-to-noise ratio. (S/N) There level lower, cause interference, in mono with less. the because of phase noise of the 2-back phase.
How to Build a Passive Bandpass Filter Circuit

The high-pass filter design creates the lower cutoff frequency point. In the circuit, we want the lower cutoff frequency point to be 1KHz. Therefore, the high-pass filter passes all frequencies above 1KHz. The formula for calculating the lower cutoff frequency is, frequency= 1/2πR1C1= 1/2π (150Ω) (1μF)= 1061 Hz≈ 1KHz.
