ABSTRACT:
The tendency for a sample-and-hold stereo multiplex demodulator having sampling pulses with low duty ratios to deemphasize the high frequency characteristics of the demodulated right and left signals is compensated for by connecting a pair of amplifiers to the right and left outputs and emphasizing the high-frequency characteristics thereof only during stereo reception.
