The cathode ray oscilloscope is an electronic test instrument, it is used to obtain Cloze (1): electrical signalsamplitudeoscilloscopeOscillographwaveformsfrequencyime interval JXUwMDJmJXUwMDE2JXUwMDE3JXUwMDEzJXUwMDAzJXUwMDA5JXUwMDFkJXUwMDFmJXUwMDFl when the different input signals are given. In the early days, it is called as an Cloze (2): electrical signalsamplitudeoscilloscopeOscillographwaveformsfrequencyime interval JXUwMDE3JXUwMDNjJXUwMDEwJXUwMDBhJXUwMDA1JXUwMDAwJXUwMDAzJXUwMDA4JXUwMDE1JXUwMDEzJXUwMDExJXUwMDE4 .

By seeing the waveform, we can analyze some properties like Cloze (5): electrical signalsamplitudeoscilloscopeOscillographwaveformsfrequencyime interval JXUwMDM5JXUwMDBjJXUwMDFkJXUwMDFjJXUwMDA1JXUwMDFkJXUwMDAxJXUwMDExJXUwMDAx , Cloze (6): electrical signalsamplitudeoscilloscopeOscillographwaveformsfrequencyime interval JXUwMDNlJXUwMDE0JXUwMDE3JXUwMDE0JXUwMDA0JXUwMDEwJXUwMDBiJXUwMDBkJXUwMDFh , rise time, distortion, t Cloze (7): electrical signalsamplitudeoscilloscopeOscillographwaveformsfrequencyime interval JXUwMDMxJXUwMDA0JXUwMDA4JXUwMDQ1JXUwMDQ5JXUwMDA3JXUwMDFhJXUwMDExJXUwMDE3JXUwMDA0JXUwMDE3JXUwMDBk and etc.
