Recorder for side-by-side digital recording of analog data and digital data

摘要

A recorder which records analog input waveforms and converts analog input data into digital data at regular intervals and at selected times records the digital data in the form of a list of data along side of the analog input waveforms together with the time and other information. When analog waveforms and characters are recorded in side-by-side relation, the speed at which the paper is fed is changed from that employed when only analog waveforms are recorded, whereby the list of data can be quickly recorded.
