Abstract
An RC active allpass section with adjustable characteristics is developed, in which the amplitude response is highly insensitive to amplifier bandwidth restrictions. It is shown that both the poles and zeros of this network migrate as a function of the amplifier gain-bandwidth product in a constant-Q manner.
