Phase Modulation and Intermodulation in Feedback Audio Amplifiers

The recently published theory on feedback-generated phase modulation is reviewed, and the magnitude of closed-loop phase nonlinearity is calculated for various amounts of open-loop amplitude nonlinearity. A measurement method for this effect is outlined, and typical measurement results are shown.
