ABSTRACT:
A system is provided in which an analog storage device stores, delays, and/or changes the time scale of an input analog waveform. The system provides an output which is corrected for the gain and offset of the analog storage device by exercising the system using known analog inputs and combining the output so obtained with the uncorrected output of the input analog waveform. In a preferred embodiment, the output is also corrected for non-linear and dispersive distortion of the storage device by exercising the system using an input analog signal derived from the earlier output of the system (corrected for gain and offset) and suitably combining the new output so generated with the earlier output.
