Abstract

PURPOSE: To increase the SN ratio of the monitor reproducing output, by providing the filter circuit passing through only the band less than a given frequency with the reproducing circuit, at low speed monitor reproduction.
CONSTITUTION: At low speed monitor reproduction for tape edit, the selector switches 19, 20 are selected so that the low pass filters 17 and 18 are inserted. To know the content recorded, it is practically sufficient at the speed 1/7 to 1/8 of the recording speed. Taking the recording frequency as f, the monitor reproducing output frequency is about f/7 to f/8, and the reproducing output level is decreased in proportional to the tape speed. Accordingly, the use of filters for the output other than output frequency is more effective to reject noises especially at high frequency region to increase the signal-to-noise-ratio (S/N).
