Direct and reversible synchronization unit for one-channel magnetic record.
Some principles and the practical application of a system making possible direct and reversible synchronization of one-channel magnetic record are described. The system makes possible superimposition of a simple synchronizing impulse upon magnetically recorded physiological process. The system is provided with an electromagnetic synchronizing relay started either with external signal during magnetic recording of experimental procedures or reversibly with a signal programmed in advance. The contacts of the electromagnetic relay could be used for simultaneous control of various systems of data processing.
