Delay Line for Stereophonic Broadcasting
A system for broadcasting programs in compatible stereophonic sound has been developed at the Bell Telephone Laboratories by F. K. Becker. The method requires that two audio channels, A and B, be delayed with respect to each other by approximately 10 milleseconds. A delay line to accomplish this time delay is described, as well as design parameters, such as phase and amplitude response vs frequency, attenuation, harmonic distortion, shielding, and the measurement of the delay time.
