i want to ask how to calculate cutoff freq for cascade RC filter
for simple low pass filter transfer function will be 1/(1+jwRC)
cutoff freq equation is w= 1/RC
that's for basic 1 resistor and 1 capasitor low-pass filter
so if i got a cascade RC network... how can i calculate cutoff freq?
Hi,
Each cascade stage will contribute one pole in the overall sytems performance.
The freqeuncy response depends on which stage contributes the dominant pole.
