Improves discrimination of f-m signals from magnetic tape, with fastest possible response to wide-deviation frequency-modulated transients. Constant reference frequency is recorded on one tape channel. When playback output voltage is made proportional to quotient of data and reference frequencies, output is independent of tape speed, and wow and flutter components are cancelled. Reference discriminator shown provides voltage output proportional to period of preceding cycle. -P. S. Bengston, Sampling Discriminators for Data Reduction, Electronics, 32:13, p 70-72.
