A channel’s maximum throughput as a function of symbol rate and bandwidth. A channel’s maximum throughput as a function of noise interference. How throughput considerations go all the way back to the ...

The concept behind digitizing sound. Working at Bell Labs, Harry Nyquist discovered that it was not necessary to capture the entire analog waveform, and samples of the wave could be taken at various ...

As an engineer at Bell Laboratories, Harry Nyquist did important work on thermal noise (“Johnson–Nyquist noise”), the stability of feedback amplifiers, telegraphy, facsimile, television, and other ...

In previous installments of the AudioFile, we've talked about basic PCM audio, which encodes audio into a series of numbers that a computer can play or manipulate. We've also discussed the process of ...
