Abstract
A method and apparatus for replacing invalid samples of an equidistantly sampled signal with corrected samples derived from an environment of valid samples preceding and following the invalid samples. The values of the corrected samples are estimated by first determining a quantity q representing a number of samples corresponding to the periodicity of a segment of the signal over an interval including valid samples and the invalid samples. Such quantity q is utilized in a system of autoregression equations in which the corrected sample values are unknown quantities, and such equations are solved by a microprocessor to derive estimates of such sample values on a 'real time' basis. The method can be applied to achieve restoration of a speech signal in which there may be intervals of up to approximately 12 msec containing invalid samples.
