In addition to finding the amplitude of a voltage and its frequency, an oscilloscope can capture and differentiate the different alternating currents from the main one. In addition, it makes it possible to identify failures present in a signal.
An oscilloscope is commonly used in the field of electronics, but it can also be used to measure different phenomena that change over time, such as:
The strength of a sound.
Vibrations.
The electrical activity of nerves.
Breath rhythm or blood pressure.
