Low-Pass Filters. As their name suggests, low-pass filters block high frequencies while allowing low frequencies through the circuit. Low-Pass Filter: For more information on calculating component specification values, see here. High-Pass Filters. High-pass filters perform the opposite function, permitting high frequencies and blocking low ones.

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. Practically in microphones, speakers, loudspeaker or audio systems we have audio amplifiers.

Band rejection filter circuit using TL071. The band rejection filter circuit is not wide filter that can denial the frequency up to 60dB by we used the TL071 single chip op-amp it is very low distortion and work good at output to maximum to 100kHz or the range 1Hz to 20kHz. In the circuit we defined three resistors R1,R2,R3 are like value to 100K, and then two capacitors …

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 …
