High Pass/Low Pass Filter Calculator (RC Filter)
Jack Orman designed this calculator years ago, I've included it here in case you should ever need to use it and can't get to Jacks website.

LOW 
PASS
FILTER

 
HIGH
PASS
FILTER

The simple R-C filter rolls off the frequency response at 6 dB per octave above the cutoff frequency. The position of the resistor and capacitors are different from low pass to high pass but the same calculation applies to both filters. This calculator assumes a low source impedance, which usually is small enough that it does not change the corner frequency.

Resistor (ohms)


*1k=1000
100k=100000
1m=1000000

Capacitor (uF)


.01uf= .01
100pf= .0001
47uf= 47

Corner Frequency (Hz)

*Original Design by Jack Orman of www.Muzique.com
