Answer by Marcus Müller for Why are linear phase filters called so, if they...
Your premise is wrong. Linear phase filters offer linear phase.Phase is not the same as time delay – at $f_1$, time delay $t$ will lead to a phase of $\varphi_1=-\omega_1\cdot t$, whereas at $f_2$, the...

Linear phase filters delay all frequencies by the same amount. Why aren't they called Constant phase filters instead of Linear phase? As I understand, if there is an input signal with two components...
