Digital Receiving Devices with Time-Division Multiplexing for Bandwidth Extension

This article presents the results of a study of the method of bandwidth extension of digital devices based on the time-division multiplexing of input signals. The simulation of digital receiving devices with a quadruple bandwidth extension is performed. The article presents the results of the study of the dependence of the spectral characteristics of receiving devices with time-division multiplexing on the error value of the aperture error and the time delay between the channels. Methods are proposed for minimizing the jitter and time delay for the practical implementation of the method of time-division multiplexing.
