12.3.6.3 Common Uses Of Anti-Resonance Filters
Low pass filters in the feedback path. This is a common way to deal with noisy feedback sensors. When
used in combination with noisy feedback sensors, significant reduction in audible noise can result.
Lead / lag filters in the forward path. This is a common way to achieve phase lead for control loops without
exciting high frequency resonances.
Low pass filters in the forward path. This is a common way to limit high frequency energy from reaching a
system that can not productively use energy at these high frequencies. This is also used to lower the
effect of system resonances over a wide range of frequencies.
Notch filters are used to cancel system resonances. Notch filters are designed to be the opposite in ampli-
tude of system resonances. Notch filters are applied to very specific frequencies, and therefore you must
know your system resonance frequencies accurately to use them effectively.
