Delta modulation in instrumented spectral analysis
Abstract
The features of spectral analysis with delta modulation are examined, and the use of the thinning operation in digital DM filters is considered. New convolution algorithms are proposed which combine DM and PCM formats for application to various types of nonrecursive and recursive digital filters. Attention is also given to a method for computing digital DM bandpass filters, and to a method for determining the pulse characteristics of DM nonrecursive filters.
