The Lead Filter can be used to add a lead in the phase response of a linear system.

Gain K: The filter gain K determines the low frequency gain of the filter.
Frequency f1: The lead in the phase response of the filter starts at frequency f1 in Hz. This corresponds to a differentiating behavior in the magnitude response from frequency f1.
Frequency f2: The lead in the phase response of the filter stops at frequency f2 in Hz. This corresponds to a constant gain in the magnitude response of the filter after frequency f2.
