ABSTRACT:
An a.c. input signal is supplied to at least one input terminal to which at least one rectifier is connected for converting the a.c. input signal to a d.c. signal corresponding thereto. A plurality of transistors are connected between the at least one rectifier and a general purpose integrated circuit with a threshold value. Each of plural transistors is controlled in its on/off operation by the d.c. signal from the rectifier in order to control the output potential of the integrated circuit. A plurality of indicators are connected between a d.c. power source and outputs of the integrated circuit to be discretely and sequentially energized to indicate a peak level of the a.c. input signal.
