What is the equation for a low-pass filter?

The cut-off frequency or -3dB point, can be found using the standard formula, ƒc = 1/(2πRC). The phase angle of the output signal at ƒc and is -45^o for a Low Pass Filter.

What is low-pass filter example?

Low-pass filters have applications such as anti-aliasing, reconstruction, and speech processing, and can be used in audio amplifiers, equalizers, and speakers. Low-pass filters can also be used in conjunction with high-pass filters to form bandpass, band-stop, and notch filters.

What is a low-pass filter in statistics?

A lowpass filter is one which suppresses or attenuates the high frequency components of a spectrum while 'passing' the low frequencies within a specified range.
