THE NOISE-IMMUNITY AND EFFICIENCY OF A DIGITAL-ANALOG METHOD OF ANALOG DATA-TRANSMISSION BY MEANS OF MULTISTAGE NONUNIFORM SIGNAL COMPOSITION

A pulsed method of transmitting analog data in which n/2 radio pulses contain information on the data samples (in accordance with Kotel'nikov's theorem) is examined. The quantization errors of the odd and even samples are transmitted by means of phase and pulse-time amplitude modulation. The noise immunity and information efficiency are determined for the case of a Gaussian communications channel and stationary messages with a uniformly limited spectrum and a uniform probability distribution.
