Abstract
Abstract In a complex sound wave wherein the information bearing group of resonances vary within different frequency regions in the sound spectrum, the detected signals derived from said group of resonances are regrouped in prearranged numerical combinations sequentially until a reference regrouping is established for neutralizing said variations.

A signal conversion system for a complex group of signals comprising a complex input signal, a plurality of bandpass filters and means for producing a control pulse, said input signal being applied to both said filters and said control pulse means, a plurality of and-gates, the complex signal output of each bandpass filter being applied as the first input to a corresponding one of said and-gates, said plurality of and-gates forming one channel of a plurality of channels, a pulse distributor providing a sequence of pulse outputs, the output of said control pulse means being connected to said pulse distributor, each pulse output from said distributor being applied to a second input of only a preselected one of said andgates in each of said plurality of channels whereby only a single and-gate in each channel has an output at one instant and each sequential output pulse of said distributor operates a different and-gate in each channel, the output of each and-gate represents the respective channel output at one instant, a signal decoder, the outputs of each channel being compared by said signal decoder, the output of said decoder being produced when a predetermined relationship between said channel outputs is detected.
