An all-pass filter is a signal processing filter that passes all frequencies equally in
gain, but changes the phase relationship among various frequencies. It does ...
second-order allpass filters, require only one operational amplifier (op amp).
Allpass ... Figure 3 and Figure 4 summarize design equations for various active
