Device for displaying electrical signals of the periodic and/or synchronizable type

摘要

A device for displaying an electrical signal of the periodic and/or synchronizable type. The main characteristic of this device is that it comprises: a memory in which this electrical signal is sequentially memorized; a recognition circuit for recognizing a predetermined electrical pattern and which emits a synchronization signal whenever the electrical signal to be displayed corresponds to the predetermined electrical pattern; microprocessor means which correlates the synchronization signal with the electrical signal to be displayed and memorized in the memory in such a way as to identify in the memory a plurality of cycles of the signal to be displayed; a cathode ray tube having a screen on which the various cycles of the memorized signal can be displayed; and processor means which convert the memorized signal into horizontal (x) and vertical (y) deflection signals of the cathode ray tube, the processor means being operable to derive, for each cycle of the memorized signal corresponding values of the deflection signals in such a way as to generate on the screen of the cathode ray tube a juxtaposed and perspective representation of the wave forms of the cycles of the signal to be displayed.
