“Scientists and engineers have been concerned with signal and noise since the early days of radio and telephone communications. Noise in electronic systems has come under intense scrutiny in recent times, especially since the amount of electronic information we process and transfer is enormous.”

“Signal and noise are also important in biological systems. In communications within the body itself, in maintaining health and avoiding disease, signals are vital. If inappropriate signals are processed in the body, this may result in a disease. Further, biophysicists trying to understand life and death from a fundamental perspective, have formulated that ‘signals’ and their processing are compatible with life while noise and its proliferation constitutes death itself.”

“Any organized system requires transmission and interpretation of specific signals. When signals breakdown, and when noise overtakes the signals, then chaos results and disorder prevails. If it is transitory, health could be restored. If it is permanent, then death might result. In fact, one might posit that life is a constant struggle to maintain a certain amount of signal in spite of ongoing noise.”

“Thus, we see in physics and in biophysics – in the world around us and the one within us – that reduction and possible elimination of noise is an important task. We define a parameter called Signal-to-Noise ratio or simply S/N which should be larger than 1. In other words, signal should always be larger than the noise. In most physical systems, we operate in a way to maintain this condition. If S/N is less than 1 (signal smaller than noise), we are running into trouble. Under these conditions, a physical system will become useless, and a psychophysical system will become sick. Thus, reducing noise and preserving the integrity of a signal are necessary in many areas of human endeavor…..”

…”Noise is a fundamental property of all physical systems that operate at finite temperatures. Even the best electronic chips, manufactured under the most stringent conditions exhibit noise. This is due to the fact that in the atomic and molecular make up, ever so small imperfections make the electronic flow random, and hence the material becomes noisy.”
