DEVICE FOR THE TRANSMISSION OF SYNCHRONOUS PULSE SIGNALS
First Claim
1. A pulse transmission receiver for bandwidth limited modulated pulse signals having a carrier frequency that is on integral multiple of the clock frequency, said receiver comprising a local clock pulse generator, an inverter, means to couple said signals to said inverter, a first sampLer coupled to said inverter, a second sampler, means to couple said signals to said second sampler, two adjustable reference voltage sources coupled to said first and second samplers respectively, said sources being adjustable in accordance with the type of modulation of said pulse signals, said first and second samplers comprising means for directly sampling said modulated pulse signals and being controlled by said local clock pulse generator, and a pulse regenerator coupled to said first and second samplers.

Abstract
A receiver for a synchronous pulse signal formed with the clock, carrier, and shift frequencies having mutual ratios of integers. The receiver has two channels controlled by a clock pulse generator synchronized to a received signal and followed by a pulse regenerator. The receiver is well suited for an embodiment using integrated circuits.
