Optical Nyquist pulse generation and transmission have emerged as pivotal technologies in the pursuit of maximising data throughput and optimising spectral efficiency in modern fibre‐optic ...

Digital instruments sample analog waveforms and operate on the samples with the assurance that the data can be restored to continuous analog form. The sampling theorem states that a signal digitized ...

A block diagram of a typical sampled data DSP system is shown in Figure 2-1. Prior to the actual analog-to-digital conversion, the analog signal usually passes through some sort of signal conditioning ...

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 ...
