Memory circuit for electrical signals - is esp. for oscillogram signals and uses analogue=digital and digital=analogue units in circuit with comparator and synchroniser

摘要

The storage circuit for electrical signals includes a logic element (2) incorporating an analogue to digital converter. Between a Y input (3) and the logic element (2) is an input amplifier (4), a sensor (5) and a comparator (6). The logic element is also coupled with a control unit (7) regulated by an adjustable timer (12) with a reset key (13), and also operating the trigger circuit (8). Another line from the logic element (2) leads through a D/A converter (14) to an output amplifier (15) and a dot liner (16) with a Y output (17). There is a direct line from the logic circuit to a synchroniser (18).
