High Pass EQ Circuit
The frequency response shown in Figure 9 shows the transfer
function of the filter calculation. The cut-off frequency is close
to 20Hz even though we selected a slightly different capacitor
than the calculated one. Therefore it is no problem for an
application to select an approximated component value.
Stereo Line Input: This figure shows the circuit diagram for the line input high pass EQ circuit.
