发明名称 Human voice analyzing apparatus
摘要 The analyzing apparatus includes a ten stage, all-zero lattice digital filter formed on a single semiconductor chip. A partial correlation coefficient is derived in each stage of the lattice filter in improved coefficient circuitry and the analyzer provides the ten partial correlation coefficients, for a best sample from a plurality of samples, along with the amplitude (R.M.S.), and the residual energy, or the excitation. The correlator uses the products FB, F2 and B2, of the residual F and B signals.
