Contrast analog signals with digital signals.

What will be an ideal response?


An analog signal is one in which the waves vary continuously-in other words, the waves have no breaks in them. A digital signal consists of discrete or separate pulses, as opposed to an analog signal, which is continuous. A digital signal has numerous starts and stops, on and off-like Morse code, for example, with its series of dots and dashes.
