Sub-Nyquist sampling and Finite Rate of Innovation (FRI) signal processing represent a paradigm shift in the acquisition and reconstruction of signals. Traditional sampling theories require adherence ...

For signals in the first nyquist zone, using the above equation to determine the location of a fundamental and its first nyquist zone harmonics is straightforward. However, determining the ...

When electrical engineers hear the name "Nyquist," they think of what Harry Nyquist is best known for: his Sampling Theorem. Evidence of its importance is everywhere. Products like cell phones, audio ...

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 ...
