Corrective Networks for Feedback Circuits

Design information is given or simplified corrective networks for application with negative-feedback devices. The corrective networks are applied to control the cutoff attenuation characteristic of the feedback transmission loop to prevent oscillation. To provide a design factor of safety against oscillation, the cutoff transmission characteristic should not attenuate at a rate of more than 10 decibels per octave. Corrective networks are required to achieve this attenuation rate.
