7.2.3.1 High-Pass Frequency Scaling Procedure

Choose a standard capacitor value and scale the impedances in the circuit according to the desired cutoff frequency (300Hz) as follows:

Equation 8. C=C1=C2
Equation 9. Z= 12πfcC=12π×300Hz×6.8nF=78.05kΩ
Equation 10. R1= Z×R1normalized=78.05kΩ×10.707=110.4kΩ

A standard value of 110kΩ is chosen for R1.

Equation 11. R2= Z×R2normalized=78.05kΩ×11.414=55.2kΩ

A standard value of 54.9kΩ is chosen for R2.
