This paper describes an application of DSP in the Human-computer interactive technology based on SEMG. DSP is used as the core of the system, using AD976 as the A/D converter. Using DSP processes the collected SEMG signal and feature extraction. Adopting some simple and easy method to classify the feature values, converted the different actions to the corresponding control commands, then send the commands to the robot, achieved the human-computer interactive technology based on SEMG. The practice has proved that this program has high feasibility and high application value.

Three-phase motors are widely used in industrial and agricultural production. However, when phase failure takes place in three-phase motor, it can be a considerable hazard on the motor. But through a simple and practical improvement of protective circuit, the phenomenon of burning motors can be effectively prevented.

A modified multi-feature voiced/unvoiced speech classification method is presented. The method is based on statistical analysis of wavelet-based frequency distribution of the average energy, zero-crossing rate, and average energy of short-time segments of the speech signal. The method first classifies the input speech into voiced, unvoiced and uncertain parts by comparing features with predetermined thresholds. Then, the uncertain parts are treated in three conditions and the boundary between voiced and unvoiced speech parts is determined by the average energy feature. The performance of the method has been evaluated using a large speech database. The method is shown to perform well in the cases of both clean and noise-degraded speech.
