- A signal is an information that has been converted into an electrical form suitable for transmission. Analog and digital signals are the two types of signals.
- The primary distinction between the two signals is that analog signals contain continuous electrical signals that represent physical measurements, whereas digital signals contain non-continuous electrical signals.
- The strength of the radio wave, for example, varies in proportion to the volume of the original sound in AM radio.
- Sine waves represent analog waves, which record sound waves exactly as they are.
- Human voice, natural sound, and analog electronic devices are all examples of analog signals.
