High Pass Filter Calculator

Calculate cutoff frequency and frequency response for an RC high pass filter.

Resistance (Ω)

Capacitance (nF)

Frequency (Hz)

Cutoff Frequency (fc)

1.59 kHz

-3dB rolloff

Magnitude @ 1.00 kHz

0.5320 (-5.48 dB)

Phase @ 1.00 kHz

57.86°

fc = 1 / (2π × R × C)

|H(jω)| = (f/fc) / √(1 + (f/fc)²)
