(1) In communications, a random interference generated by the movement of electricity in the line. It is similar to white noise, but confined to a narrower range of frequencies. You can actually see ...

Although much telecom testing involves additive white Gaussian noise (AWGN), white noise does not need to be Gaussian, nor is Gaussian noise necessarily white. White noise is defined by two ...

Every electronic circuit has some noise and it can affect both analog and digital circuits. Some noise comes from outside interference while some comes from random factors such as thermal effects.
