DSP - Digital Signal Processing
Introduction
Digital Signal Processing uses software techniques to accomplish many things that have traditionally been accomplished in hardware, plus a number of things that cannot easily be done using physical components. Once a signal is converted to digital form, DSP software can filter it, shape it and process it to remove noise.
With Signals, Samples and Stuff: A DSP Tutorial -- Part 1 you will find a four part series on digital signal processing.

Bibliography (Members Only)
ARRL Periodicals Index Search - This database contains the QST index from 1915 to the present and the QEX index from 1981 to the present. For QST issues from 1970 to the present, and some selected articles back to 1922 (when construction articles featuring tubes began in earnest), identifying keywords have been added to the technical articles. By entering keywords (ANTENNA) or combinations of keywords (CONSTRUCTION ANTENNA VERTICAL HF) into the Title words: field, you may create dynamic bibliographies.
