Abstract :
A short-time spectrum analyser (SA) for applications in speech analysis acoustics and other topics is proposed. The SA is an heterodyne, 2-phase type based on delta-sigma modulation (DSM). The use of DSM simplifies the hardware realisation and increases the accuracy of the analysis. The analyser has been tested, and the results obtained verified the expected performance.
