Class Information
Number: 330/94
Name: Amplifiers > Signal feedback > Cathode impedance feedback > Frequency responsive means in cathode impedance feedback path
Description: Subject matter including in the "cathode impedance to ground signal feedback path" or in shunt therewith circuit means which acts on the signal feedback to affect some frequency component of the signal feedback differently from the other frequency components of the signal feedback, for example, a tuned circuit or filter circuit which eliminates a frequency component, or an equalizer which emphasizes or de-emphasizes the signal feedback amplitude of some frequency or frequency range of the signal feedback with respect to others.
