Abstract
PURPOSE:To facilitate an eacy monitor for several levels by selecting successively the level monitor output according to the selection signal sent from the gate synchronizing circuit. CONSTITUTION:Level monitor outputs 1a-1n are supplied to level meter 10 via gate circuits 2a-2n, level monitor switching circuit 7, filters 8a-8l and coupling circuits 9 each. Gate synchronizing circuit 6 generates the selection signals to give the control to gates 2a-2n plus circuits 7 and 9 each. With this selection signal, the level monitor output is selected successively to facilitate an easy monitor for several levels by one unit of the level meter.
