👉 Gilbert's Law, also known as Gilbert's Theorem, is a principle in information theory that states that in any communication channel (such as telephone or radio), if the signal-to-noise ratio (SNR) of the transmitted signal exceeds some critical value, then the probability of receiving an error (or more accurately, the probability of detecting an error) will increase exponentially with the distance between the transmitter and receiver. This principle is named after the American physicist John G. Gilbert, who
