Different measurements with a SAW convolver and description of a code generator (PRBS) generator
Abstract
Measurements with a surface acoustic wave piezoelectric monolithic convolver, which allows the correlation of codes up to 1000 or more chips in length at chip rates from a few MHz to over 100 MHz with essentially instantaneous programmability are described. Most of the measurements were made using a pseudo random binary sequence (PRBS) code generator which can produce two maximum length codes, the one opposite-in-time to the other. Operating instructions and a literature survey are given.
