Title: Electronic time switch
IPC: H03K17/28
Filed: 1976-06-16
Abstract: The timing switch described transfers the edges of normalized square wave pulses with delay. In this arrangement, either only the positive or only the negative edges or both edges are optionally delayed by a predetermined time which results in a high degree of immunity to interference signals. The timing switch contains a basic circuit, acting as multivibrator stage, with an operational amplifier (E) operating as analog integrator and a switching transistor (Tr) and an additional circuit, equipped differently depending on the desired delay mode, of diodes (Z1, Z2, D1-D3) and of fixed (R4, R5) and variable (P1, P2) resistors. This additional circuit forms feedback for the multivibrator stage and thus determines the transfer characteristic of the timing switch. The operating delay can be predetermined at the potentiometer (P1) and the drop-out delay can be predetermined at the potentiometer (P2). <IMAGE>
