Flip-flop sampling pulse generator supplies 5-mlcrosec pulses at 3-kcprr to modulator that also has analog signal input. Integrated difference signal fires Schmitt trigger to provide positive output that opens gate, passing square-wave pulse that sets flip-flop. Output of flip-flop is fed to emitter-follower and demodulated by ac five low-pass liter having 50-cps cutoff.-H.
