MAGNETIC_TAPE_DATA_SAMPLER
Used in playback system for discrimination of f-m signal from magnetic tape. Compares data channel signals with recorded reference frequency, to make output independent of tape speed. Tube V2B is cathode follower with hyperbola generator network as cathode impedance, to create curve for average area of voltage block at any time during data period for a given block width (1.4 millisec).-P.
