The high-pass filter is designed using a capacitor (“C1” in the circuit diagram) of 100 nF and a resistor (“R2”) of 3.2 kilo-ohms. Using these values for the capacitor and resistor, the cut-off frequency of the filter can be calculated as follows: FH= 1/ (2πR2C1) FH= 1/ (2π*3.2k*100n) FH= 500Hz (approx.)
