AES Convention 55 · Paper 1185 · October 1976

Abstract

A description of the sine-square intermodulation measuring method is given. The practical measuring procedure is described, and measurement results of commercial audio power amplifiers, and integrated operational amplifiers are presented, in many cases showing appreciable transient intermodulation in units which have excellent total harmonic distortion and SMPTE intermodulation distortion specifications. The correlation of these measurements with results obtained using other methods, such as CC17-1M and the noise-transfer method, is treated, and the interdependence of these with the slow rate and the power bandwidth is discussed.
