In information theory: Continuous communication and the problem of bandwidth …to bandwidth-limited signals is Nyquist’s sampling theorem, which states that a signal of bandwidth B can be reconstructed by taking 2_B_ samples every second. In 1924, Harry Nyquist derived the following formula for the maximum data rate that can be achieved in a noiseless channel: Maximum Data Rate = 2… Read More

In telecommunication: Sampling …commonly referred to as the sampling theorem, and the sampling interval (1/2_B_ seconds) is referred to as the Nyquist interval (after the Swedish-born American electrical engineer Harry Nyquist). As an example of the Nyquist interval, in past telephone practice the bandwidth, commonly fixed at 3,000 hertz, was sampled at least… Read More

In Harry Nyquist …and established the principles of sampling continuous signals to convert them to digital signals. The Nyquist sampling theorem showed that the sampling rate must be at least twice the highest frequency present in the sample in order to reconstruct the original signal. These two papers by Nyquist, along with one… Read More
