In sub-band divisions of speech sound waves the detected signals derived from the sub-bands are continually regrouped at the outputs of a numerically arranged bank of channels in an order that, the signal derived from the lowest frequency (pitch) in the sub-bands is continually shifted to the output of the first channel, while the other signals are shifted to the numerically positioned channel outputs by the same factors of multiplication from the first channel as the other sub-bands differ from said lowest frequency. |
