The circuit illustrates the use of 3 frequencies to produce a graphic equalizer that will be used for acoustic signals. Equalizer – a passive or an active electronic element or circuits (like tone ...
This one is a 10 band graphic equalizer circuit based on TL074 low noise JFET op-amp. As shown in the diagram, there are 10 same units that only differ in capacitance values of capacitors which ...
