An audio filter circuit is a broadband filter and is also called a wide bandpass filter because its bandwidth is restricted to the audio frequency. Audio filter circuit can be formed by simple cascading high pass filter circuit and low pass filter circuit and is generally the choice for simplicity of design and performance through such a circuit can be realized by a number of the …

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 …

NE5532N This audio noise filter circuit is a bandpass filter for audio frequency band. It filters unwanted signals that are lower or higher than the audio frequencies. It has 2 filters: a low pass filter and a high pass filter in a cascade configuration. Both filters are second-order filters with a 24 dB/octave fiter capability.
