ABSTRACT:
A remote recording and playback system comprises a recording unit for recording analog data received virtually simultaneously over a plurality of analog input channels, and a playback unit for playing back said recorded analog data for a given one of the plurality of analog input channels. The recording unit sequentially scans the plurality of analog input channels in succession to derive respective analog data samples, converts the respective analog data samples to digital form, and stores the digital representations of the analog data samples in a random access memory. The playback unit accesses the random access memory in the recording unit, converts the digital representations derived therefrom to analog signals, and displays the previously recorded analog data, one channel at a time. The system is further characterized by the storage and retrieval of "drift" and D.C. offset data, visual display by the playback unit of the channel number for which digital data is being displayed, and recharging of the recording unit by the playback unit during connection thereto (for example, during playback).
