Abstract
A method is described which enables video signals to be transmitted by the pulse code modulation system known as delta-modulation. A tunnel-diode balanced pair (Goto pair) is used for converting the video signal into a binary signal. With a new and very simple circuit, operating at a bit rate of 100 Mc, a ratio of signal-to-quantizing noise of 42 db is obtained. A more conventional circuit, that combines tunnel-diodes with transistors, makes an even lower quantizing noise possible.
