A Method for Measuring Transient Intermodulation Distortion

Document Thumbnail

A description of the square-sine 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 and total harmonic distortion and SMPTE intermodulation distortion specifications. The correlation of these measurements with results obtained using other methods, such as the CCIF-IM and the noise-transfer method, is treated, and the interdependence of these with the slew rate and the power bandwidth is discussed.
