Digital Pre-Processor for the Portable Channel Prober Measurement Instrument.
Abstract
This document describes a Digital Pre-processor for the Portable Channel Proper Measurement Instrument being developed by the Naval Research Laboratory for use in experiments designed to characterize high frequency (HF) radio channels. This Digital Pre-processor is a digital signal processor designed and constructed by Stow Computer, 111 Old Bolton Road, Stow, MA 01775, (617) 897-6838. The Digital Pre-processor will be located at the receiver site of the channel probing experiment and is situated between the receiver and the microcomputer used for data recording and analysis. The Digital Pre-processor performs functions that cannot practically be performed by the the general purpose microcomputer. The Digital Pre-processor coverts the analog output of the receiver to digital data for processing, recording and analysis. It performs digital data for processing, recording, and analysis. It performs digital signal processing on the data before recording or analysis by the general purposes microcomputer. It may perform data reduction to reduce the volume or rate of data. The Digital Pre-processor described is described for portable use. It is small enough to be used on a table top or may be mounted in a standard equipment rack.
