RC High-pass Filter

This is a RC High-pass filter. Use this equations to calculate the Transfer Function for filter at a given frequency or values of R and C.

>> Calculate the transfer function for the filter with R and C values.
 

>> Calculate the R and C values for the filter at a given frequency.

Note : Use R as Ohms (Ω) and C as farads (F), then Fc will be hertz (Hz).

See below for frequency response of above filter that designed for 20Hz  cutoff frequency.

R = 8.2kΩ
C = 1uF

Cut-off frequency     fc =  19.4091394015 Hz  = 20 Hz
