    This paper presents a new method of speech coding that takes advantage of the repetitiveness inherent in voiced speech. Voiced speech is broken into pitch period lengths (wavelets) and these signals are compared with one another to determine If two wavelets differ significantly. If the wavelets are significantly different, then they are encoded and transmitted; otherwise, the current wavelet Is no... View full abstract»

    There has been a lot of interest in using higher-order statistics (such as cumulants) in signal processing and system identification problems. There are several reasons behind this interest. First, higher-order cumulants are blind to all kinds of Gaussian processes, hence cumulants suppress additive colored Gaussian noise. Therefore if the signal to be analysed is contaminated by additive Gaussian... View full abstract»

    The presence of a nonlinear capacitor in a circuit model mathematically implies the existence of a parallel transcapacitor, if the value of its capacitance is a function of a remote voltage. As a consequence, simulating small-signal excursions with a nonlinear model produces data which is inconsistent with the simulations using the small-signal model, if the latter does not include the transcapaci...
