For the pitch misgrouping problem caused by no voicing decision in Meddis'pitch extracting method for concurrent speech signals, referring to voicing decision for single speech signal, basing on the analysis of the voicing charater of concurrent speech signals, we present a voicing decision method in pitch extracting for concurrent speech signals. Double periodic degree and frequencies group's distribution degree are introduced for voicing decision of concurrent speech signals.

Open Linear Encoder includes main grating scale and optical encoder head. This optical encoder head includes LED light source, optical detector module, and secondary phase-grating. LED light will pass through the plano-convex lens and produces parallel light. As the parallel light pass through secondary grating, the quadratic image display on the main grating scale. And the Moire interference will be reflected from the main grating scale and detected by optical detector module, as there is a relative shift between the main and secondary grating. From detecting the periodic sinusoidal signal with phase difference 90°, the period represents the grating pitch, using the counter to detect the number of periodic signals to get the displacement, and we can adapt the technology of electron subdivide further to increase the resolution of measurement .
