This paper systematically analysis the problem of errors of linear predictive coding. Beginning from error response, it discusses stable decay of errors. The paper also describes the relation between error energy and predictive coefficients and between the energy and the position of samples, etc. Finally it discusses the problem of minimum energy. Thus a basis for selecting a predictive design is given.

This paper presents a realization method of deconvolution algorithmto the linear time-invariant system. The choice of parameters is determined with computer analogous realization. The quadratic relative, error of restoring signal is 1 % approximately. The advantage of the deconvolution algorithm is its simplicity, the computational requirements are only 2M multiplications and 2M + 1 additions for one restoring point, where M is the sample number of impulse response. The algorithm can therefore be real-time implemented with a microprocessor for low-frequency systems. We have applied the algorithm to the restoring of ventricular pressure waveform of a guinea-pig, and good results are obtained.
