The Lag Filter can be used to add a lag in the phase response of a system.
|•||Gain K: The filter gain K determines the low frequency gain of the filter.|
|•||Frequency f1: The lag in the phase response of the filter starts at frequency f1 in Hz. This corresponds to an integrating behavior in the magnitude response from frequency f1.|
|•||Frequency f2: The lag in the phase response of the filter stops at frequency f2 in Hz. This corresponds to a constant attenuation in the magnitude response of the filter after frequency f2.|
