ABSTRACT:
A sampling device operating as a buffer between a first data signal and a relatively slow processing device accepts the input signal and stores samples of it on a SAW traveling past an input electrode. A blocking potential is applied to a set of electrodes to store a set of charge packets with the SAW device. Packets are consecutively released at a slower rate accommodated to the needs of the next processing unit in line, to read out the sampled signal at a modified rate for intentional distortion of the input signal, for slowing the output stored signal rate, or for time reversal of the signal.
