Device for gating a blanking bar into a recording of analog signals
First Claim
1. Device for gating a blanking pulse into a recording of analog signals on the recording section of a picture recording device, the analog signals being supplied (in the so-called fixed mode) by a frame repeat memory at least for a presettable period of time as a frozen waveform with circular updating and the blanking bar precessing through the recording, separating the signal beginning from the signal end in the signal waveform, characterized such that the frame repeat memory (24) contains as information for the blanking bar (ST) a stored blanking bar code (281) which, when given out from the frame repeat memory, is sent on the one hand to an actuation pulse generator (282) and, on the other, to a pulse generator (47) which upon appearance of the blanking code generates an analog pulse of fast rise time whose amplitude moreover is much higher than the highest amplitude of the analog signal (A) normally to be expected, and which sends this fast rise analog pulse of especially high amplitude to the y-deflection system (48) of the remote picture recording device, while simultaneously the z-generator (49) is activated by the scanning pulse generator (282) for application of a z-actuation pulse to the z-control section of the local picture recording device (28).
