Glottal flows and sound pressure waveforms of four different fundamental frequencies were generated using a computational model of vocal fold vibration and acoustic wave propagation in order to evaluate the performance of an inverse filtering method. Four time-based parameters of the glottal flow were used in order to assess the accuracy of the inverse filtering technique. The results show that...

The performance of decision feedback equalizers (DFE’s) working on a noiseless channel with correct tap weights is studied. We show that the space of channel parameters can accordingly be partitioned into a finite number of sets. The error recovery performance of a DFE is the same for all DFE’s within one such set, and is determinable. We also discuss some tight bounds for recovery time statist...

We are interesting in the error exponent for source coding with fidelity criterion. For each fixed distortion level ∆, the maximum attainable error exponent at rate R, as a function of R, is called the reliability function. The minimum rate achieving the given error exponent is called the minimum achievable rate. For memoryless sources with finite alphabet, Marton (1974) gave an expression of t...
