A four-quadrant time-division analogue multiplier based on a pulse-interval amplitude-modulation (PIAM) technique is proposed. This multiplier is self-triggered and thus does not require an external triangular-wave generator for its operation, unlike other time-division multipliers. A practical circuit has been designed and tested. Experimental results agree closely with theory.read more

Pulse-Interval Modulation Applicable to Narrowband Transmission
TL;DR: Comparisions with PPM and FM are made, which proves that PIM is suited for the TV signal transmission, and the differential gain characteristics and the interference outputs owing to the unwanted lower sidebands of a pulse train are examined, which indicates the effectiveness of lowpass filtering of post-detection signals.
