(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 ...

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.

All sorts of physical processes in this analog world exhibit some degree of randomness. Think of noise, for example. Many noisy processes are described by Gaussian probability distributions. We should ...
