An active RC all-pass network has been proposed in which the regulation of only one component allows independent adjustment of each parameter affecting the phase characteristic. This flexibility is very suitable for time-delay equalization. Its use in maximally flat time-delay lines is shown, and tables of normalized components are provided to simplify the design work.
