TL;DR: In this paper, the authors proposed a data compression method and apparatus particularly suitable for use in electrical power line fault data recorders, which performs both gain compression and frequency compression, and a predetermined number of samples are analyzed to determine a gain setting common to each sample in the set of samples.
Abstract: A data compression method and apparatus particularly suitable for use in electrical power line fault data recorders. The system performs both gain compression and frequency compression. For gain compression, a predetermined number of samples are analyzed to determine a gain setting common to each sample in the set of samples. A reduced data string consisting of a gain code and data words having fewer bits than the input words are transmitted as a compressed data string. For frequency compression, a sample set representing the input signal is decimated until there remain only a sufficient number of data samples to satisfy the Nyquist criterion for the highest frequency component of interest. The frequency compressed output data string comprises a frequency code representing the highest frequency of interest followed by the set of decimated data samples.

Abstract: A data compression method and appartus particularly suitable for use in electrical power line fault data recorders. The system performs both gain compression and frequency compression. For gain compression, a predetermined number of samples are analyzed to determine a gain setting common to each sample in the set of samples. A reduced data string consisting of a gain code and data words having fewer bits than the input words are transmitted as a compressed data string. For frequency compression, a sample set representing the input signal is decimated until there remain only a sufficient number of data samples to satisfy the Nyquist criterion for the highest frequency component of interest. Also included is a circuit for reproducing the waveform envelope. Positive and negative peak detectors provide signals representative of the peaks of the waveforms. These positive and negative signals are then compressed with the gain compression circuit, decompressed after transmission or recall, and then displayed as an envelope waveform for allowing trend analysis.

TL;DR: A simple and low cost hardware environment for TMS32020 development is described, designed not only as a companion to the simulation environment but is combined with it so that the change between the two is exceptionally convenient.

TL;DR: In choosing between FFT alternatives in DSP implementations, you'll need to consider the nature of the main processing device as well as execution times and cost.
