oscilloscope

what is oscilloscope oscilloscope is a laboratory instrument commonly used to display and analyze thewaveform of electronic signals. In effect, the device draws a graph of the instantaneous signal voltage as a function of time.

There are two types of oscilloscopes: Analog oscilloscopes : (used cathode ray tubes ) display the signal much like a television set displays an image. Digital oscilloscopes sample the signals digitally and are more flexible in how they display, manipulate, and store the signals.

who invented oscilloscope In 1897, Karl Ferdinand Braun invented the oscilloscope, which was an adaptation that he made to the cathode ray tube.

cathode-ray oscilloscope The earliest and simplest type of oscilloscope consisted of a cathode ray tube, a vertical amplifier, a time base, a horizontal amplifier and a power supply. These are now called "analog" scopes to distinguish them from the "digital" scopes that became common in the 1990s and 2000s.

cathode-ray oscilloscope Actually cathode ray oscilloscope is very fast X-Y plotters that can display an input signal versus time or other signal.

Cathode-ray tube  is a vacuum tube containing one or more electron guns, and a phosphorescent screen used to view images. It has a means to accelerate and deflect the electron beam(s) onto the screen to create the images.
