What is 3dB frequency in high-pass filter?

f3db = 1/(2*pi*RC)

Since this filter favors high frequencies, the graph of signal strength to frequency looks like this: With the low-pass and high-pass filters, we can accomplish a number of signal processing tasks, including selecting out a specific frequency band.

How do I fix my high-pass filter?

The cut-off frequency, corner frequency or -3dB point of a high pass filter can be found using the standard formula of: ƒc = 1/(2πRC). The phase angle of the resulting output signal at ƒc is +45o.

Should I enable high-pass filter?

If you are broadcasting or reinforcing sound outside, and even your best windscreen can't keep out the persistent low-frequency rumble from wind noise, then stopping it right at the source may be your best option. Highpass filters are excellent for this application.

What frequency should I set my high-pass filter to?

Setting the HPF and LPF

Our engineers have determined that the best starting point when pairing LS50 Wireless II to KF92 is to set the HPF to 70 Hz, and the LPF to 50 Hz.
