An Improved Intermodulation Measuring System
This paper describes a new intermodulation analyzer of improved design and also a two-signal generator for use with the analyzer. The equipment is intended for measuring distortion in audio-frequency systems by means of paired signals which may be selected in several combinations from 40 to 12,000 cycles per second. This equipment has been found to be particularly useful in determining optimum processing conditions for variable-density recording but is also useful in any field where audio frequencies are employed.
