Want this question answered?
wave is a part of a signal . millions of wave construct a signal .
1.wave is a three dimensional object where as signal is a two dimensional object
A: square wave can be positive and or negative. A digital signal is a square wave but it can be of invariable duty cycles
The difference is in sine wave generation algorithm. In HI freq - it is 30kHz signal, modulated by 50Hz.
Well, in signal processing it means to be the same most of the time. But if someone asks you to distinguish between these two, it merely means in a square wave uptime and downtime of voltage is the same whereas in a rectangular wave uptime is different from the downtime.
In wifi, modulated signal is radio wave where as life modulated signal is light. It is visible electromagnetic spectrum and has higher bandwidth than wifi but has Line of sight limitation.
A Digital Signal can have one of two values, 1 or 0. An Analogue signal can have any value between 1 and 0. Digital signals are better for sending information as if the signal is somewhat distorted, it is still easily recognisable. Vinyl Record use analogue. Cds use Digital
A coder can accept any kind of analog signal while demodulator can only accept a modulated sine wave. Then they generate the digital signal.

A wave is a normal wave and a wave length is the wave Height or distance
Wavelength.
you figure it out
