Why Visualization of Signal? Basics to Understanding Oscilloscopes

The specific characteristics of a signal can be measured by a variety of instruments. For example, a counter can measure a signal’s frequency or its period, and an ac voltmeter can measure the RMS value of the signal. Although these instruments are very useful and can be more accurate than the oscilloscope, their application is mainly limited to the measure­ment of one parameter of the signal. With an oscilloscope, one can visual­ize the signal of interest and also observe whether the signal contains properties that would not be made apparent by most other instruments (for example, whether the signal is superimposed on a de level, or whether there are noise or relative hf oscillations present with the signal at the test point). Thus the oscilloscope is a more valuable instrument because it gives an exact visual representation of the signal waveform.

Sampling Oscilloscopes

Sampling is the taking of a specimen, or a part, to illustrate the whole. For example, when a ship’s cargo of sugar must be checked for the amount (%) of water in the sugar, specimens of the sugar are taken from various places in the ship. The more specimens are taken, the more information is available about the quality of the cargo overall. It is evident that to be 100% sure about the condition of the cargo, all the sugar present in the ship would have to be checked; however, this is not possible.
