WebApr 14, 2024 · When the coefficients of a FIR filter sum to one, the output of a constant input signal will be identical to the input. Basically, a constant signal is very smooth, therefore should be left untouched by a smoothing filter. Therefore, most low-pass filters are normalized to unit sum. WebIf you take a simple lowpass RC filter, the (half-power) cutoff, or corner frequency is your $f_0$, and the pulsation, $\omega_0=2\pi f_0$ with $f_0=\frac{1}{2\pi RC}$, where RC is the time constant. This means that the time constant is directly proportional to the frequency (and pulsation), and can only have a fixed value relative to the ...
