ABSTRACT:
A system for digitally storing samples of an analog signal taken at a sampling rate, f, and for reconstructing said analog signal from such stored samples. The analog signal is separated into a plurality of, n, channels, each one of such channels having a digital storage section. Each one of the storage sections is adapted to store a sample of the analog signal in response to a sampling pulse. A pulse generator circuit is provided and supplies one of a plurality of trains of periodic sampling pulses to a corresponding one of the plurality of storage sections. The sampling pulses in each of the trains of sampling pulses have a pulse repetition frequency, f
. Further, the sampling pulses in successive trains thereof are delayed in time 1
th the period of the sampling pulses. Apparatus is provided for retrieving the samples stored in the plurality of storage sections in the same sequence as such samples were stored. The sequentially retrieved samples are obtained at the rate, f, and are combined into a composite signal, such composite signal being a reconstruction of the analog signal. By using plural channels, each one of the storage sections samples the analog signal at a rate less than that required for a single channel system.
