Abstract
Дельта-модулятор, состоящий из микрофона с усилителем, дискретизатора сигнала по времени с подключенным к его высокочастотному (в.ч.) входу генератора импульсов, а к его выходу - усилителя - ограничителя амплитуды сигнала, отличающийся тем, что в него дополнительно введены формирователь однополосного сигнала, генератор колебания вспомогательной несущей частоты, когерентный детектор, фазовращатель сигнала на 90°, причем выход микрофона с усилителем подключен к н.ч. входу дискретизатора через последовательно соединенные формирователь однополосного сигнала и когерентный детектор, а генератор колебания вспомогательной несущей частоты своим выходом подключен к в.ч. входу формирователя однополосного сигнала непосредственно и к опорному входу когерентного детектора - через фазовращатель на 90°.A delta modulator, consisting of a microphone with an amplifier, a signal sampler in time with a pulse generator connected to its high-frequency (including) input, and to its output, an amplifier - signal amplitude limiter, characterized in that a single-band shaper is additionally introduced into it a signal, an auxiliary carrier frequency oscillation generator, a coherent detector, a phase shifter of the signal by 90 °, and the microphone output with an amplifier is connected to the low the sampler input through a serially connected single-band signal shaper and a coherent detector, and the auxiliary carrier frequency oscillation generator is connected to the RF by its output the input of the shaper of a single-band signal directly and to the reference input of a coherent detector through a 90 ° phase shifter.
