Rectangular<\/strong><\/p>\n<p>A CRO (Cathode Ray Oscilloscope) is an electronic instrument that is used to display waveforms. It consists of a cathode ray tube (CRT), which is a vacuum tube that contains an electron gun, a deflection system, and a phosphor screen. The electron gun emits a beam of electrons, which is then deflected by the deflection system to create an image on the phosphor screen. The waveform to be displayed is applied to the horizontal plates of the CRO, which causes the electron beam to <div class=\"telegram-channel-container\">\r\n        <a href=\"https:\/\/t.me\/pscnotes2025\" target=\"_blank\" class=\"telegram-channel-button\">\r\n            <span class=\"telegram-icon\">\r\n                <svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 496 512\">\r\n                    <path fill=\"white\" d=\"M248,8C111,8,0,119,0,256s111,248,248,248s248-111,248-248S385,8,248,8z M362,177L320,367c-3,14-10,18-20,14l-56-41l-27,26 c-3,3-5,5-10,5l4-63L323,196c5-5-1-7-8-3l-98,62l-42-13c-9-3-10-9,2-14l162-63C351,160,365,164,362,177z\"\/>\r\n                <\/svg>\r\n            <\/span>\r\n            Join Our Telegram Channel\r\n        <\/a>\r\n    <\/div> be deflected horizontally.

However, it is not the type of voltage that is used to display the signal pattern. The signal pattern is displayed by applying a rectangular voltage to the horizontal plates of the CRO. A rectangular voltage is a type of voltage that has a constant amplitude and a constant frequency. This type of voltage is ideal for displaying waveforms because it produces a clear and sharp image on the screen.<\/p>\n<p>A sinusoidal voltage is a type of voltage that has a sine wave waveform.
