Abstract

"A procedure is presented by which it is possible to detect a known signal of unknown delay in a noisy medium contaminated by noise. From the results the characteristics of a sequency digital filter which would be required to remove the noise contamination is indicated. The Walsh functions are discussed and the sequency domain, which is analogous to the continuous frequency domain, is used in the spectral analysis of signals. The binary nature of the Walsh functions and their ease of generation makes processing of signals easier than the Fourier analysis approach. The applications of fast forward and inverse Walsh transform routines are applied in the analysis of signals. The sequency domain appears to be a more natural approach to the design of digital filters because of the pulse-shaped characteristics of the Walsh functions. The introduction of low cost digital integrated circuits makes the sequency domain approach even more attractive. The application of the method to sonar, radar, and seismic signals is very feasible"--Abstract, page ii.
