WebbThe Low Pass Filter Stage The value of the capacitor C2 required to give a cut-off frequency ƒH of 30kHz with a resistor value of 10kΩ is calculated as: Then, the values of R2 and C2 required for the low pass stage to give a cut-off frequency of 30kHz are, R = 10kΩ and C = 530pF.

WebbThis low-pass filter blocks AC and passes DC to the R load resistor. Typical of a filter used to suppress ripple from a rectifier circuit, it actually has a resonant frequency, technically making it a band-pass filter. However, it works well anyway to pass DC and block the high-frequency harmonics generated by the AC-to-DC rectification process.
