CIRCUIT FOR PRODUCING A VIDEO SIGNAL REPRESENTING A MEASURING SIGNAL |
摘要 |
<p>A Circuit for Producing a Video Signal Representing a Measuring Signal A circuit for producing a video signal representing a measuring signal is already known, said circuit comprising a video storage circuit, a horizontal address control circuit for controlling said video storage circuit, a circuit for producing a vertical signal and a comparator circuit which, when the vertical signal essentially corresponds to a signal derived from the video storage circuit, produces a comparison signal representative of a point of the measuring signal in the instantaneously produced line of the video signal. For the purpose of improving the measuring signal representation quality, the invention provides the feature that a video D/A converter and a low-pass filter circuit are inserted between the video storage circuit and the comparator circuit.</p> |
