Abstract
A method and apparatus for comparing waveshape portions of at least one time-varying signal by first forming initial templates of digital signal samples representative of the amplitude of successive time-spaced samples of portions of the time-varying signal. Next, forming reduced templates having a number of digital signal elements which is less than the number of samples in corresponding ones of the initial templates, each element of the reduced template comprising a combination of at least two samples from its corresponding initial template. And then processing corresponding elements of at least two of the reduced templates for deriving a signal representative of the degree of similarity of the respective portions of the time-varying signal represented by at least two reduced templates.
