Frequency Characteristic of a Sound-Reinforcing System
The purely electrical frequency characteristic of a high-fidelity sound-reinforcing system is smooth when the amplification is low. As the amplification approaches the -singing- point, the frequency characteristic becomes very ragged because of the randomly varying phase of the acoustic feedback from loudspeaker to microphone. This paper presents representative frequency characteristics taken under these conditions and discusses the application of this effect in the operation of systems.
