Spectral Analysis of Randomly Sampled Signals

Sync signal processing for asynchronously sampled video signals

Digital sync signal processing for asynchronously digitized video signals is presented. A simplified matched filter for sync extraction and a linear prediction method for sync pulse filtering improves image stability significantly in comparison with a conventional phase-locked-loop (PLL) approach. Due to the linear prediction method, additional adaption to phase skips in the input signal (non-s...

Methods for Spectral Analysis of Nonuniformly Sampled Signals

The key element of Digital Alias-free Signal Processing (DASP) technology is the application of nonuniform sampling. In this case majority of the conventional signal processing algorithms cannot be directly applied. For the implementation of DASP, a set of new approaches was developed. The paper discusses several approaches suitable for spectral analysis of nonuniformly sampled signals. These i...

spectral analysis of sequentially sampled signals for applications in information processing

this paper studies the sequential sampling scheme, as a solution to the problem of aliasing, where the sampling interval is restricted to a minimum allowable value d t. in the sequential sampling, the signal is sampled at intervals of d t, d t+ dt , d t+2 dt , d t+3 dt , ...; where dt < d t and may be selected as desirable. the sequential sampling is, however, analyzed and it is proven that, wh...
