Circuit having a high school bass tone function

  
Figure 4-7 pitch analysis using the relation obtained above design calculation control circuit, where Ai is a buffer to put the big stage, to reduce the burden preamp output. L
Circuit having a high school bass tone function - schematic

ow-corner frequency of the circuit is 30Hz, high frequency corner frequency of 1kHz, the control range of 20dBo not only to design an operational amplifier having a high bass control tone circuit functions, but also to design a high school bass control tone system function the control circuit, the actual circuit shown in Figure 4-9.
