Claims

[Claims for Utility Model Registration] 1. Display or record signals based on the comparison output of a comparator that inputs the digital-to-analog converted waveform signal read from the waveform memory for each horizontal scan and the vertical scan signal. In a horizontal scanning waveform display/recording device configured to generate a waveform, the above-mentioned waveform signal is inputted to one input, the above-mentioned vertical scanning signal is inputted to the other input, and a desired vertical one comparator that superimposes and inputs a pulse wave with a constant amplitude that determines the thickness of the display and a period extremely shorter than the period of the horizontal scanning, and the moment of reversal of the logic level of the output of the comparator and the pulse. A horizontal scanning waveform display/recording device that generates a display or recording pulse signal at the moment of wave reversal and is equipped with a video pulse generator composed of a delay circuit and a logic circuit. 2. A delay circuit that operates only at the moment of inversion of the logic level of the output of the comparator and the moment of inversion of the pulse wave is used, and a two-stage time constant circuit is provided in this circuit to change the logic level from "0" to "1" and the horizontal scanning waveform display according to claim 1, in which the pulse width of the display or recording pulse signal generated at the moment when "1" changes to "0" can be changed independently.・Recording device.
