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 ...

The theorem asserts that to capture all the information in a signal without losing any data, the sample rate needs to be at least twice that of the signal's highest frequency (Figure 2 Sampling Rates) ...

Finally, the decimation filter removes outband quantization noise. Further decimation process can change the oversampling rate back to the desired sampling rate for the output digital signal w (m). To ...

Figure 2. Sampled Data System: Sampling and Quantization. Here, sampling is the impact along the time domain. While quantization is the impact along the amplitude domain. the very act of sampling does ...
