Abstract: PURPOSE: A transcoding system and method for CELP(Code Excited Linear Prediction) CODECs having different bandwidths are provided to reduce sound quality deterioration and decrease delay and the quantity of calculations. CONSTITUTION: A transcoding system includes a Formant parameter converter(32), a Formant factor quantizer(34), an excited signal parameter converter(36), and an excited signal quantizer(38). The Formant parameter converter converts a Formant parameter coded in an input CELP format into an output CELP format to generate an output Formant parameter. The Formant coefficient quantizer receives a Formant filter factor in the output format from the Formant parameter converter to quantize the Formant filter factor in the format used by an output CELP CODEC. The excited signal parameter converter converts an excited signal parameter coded in the input CELP format into the output CELP format to generate an output excited signal parameter. The excited signal quantizer quantizes the excited signal parameter in the output CELP CODEC format.

Abstract: PURPOSE: A motor control method of a washing machine is provided to prevent damage of a circuit and improve stability and reliability by restricting over current from overload with controlling the duty rate corresponding to the laundry amount and RPM(Revolution Per Minute) in suddenly braking the motor. CONSTITUTION: Sudden braking is performed by plugging in inputting the sudden braking command(S21,S22), and RPM of a motor is compared with the first predetermined RPM(S23). The duty rate is adjusted with detecting time reaching the first predetermined RPM from suddenly braking the motor(S24,S25,S26,S27,S28). Time reaching from the first predetermined RPM to the second predetermined RPM is detected if RPM of the motor reaches the second predetermined RPM(S29,S30). The duty rate is decreased corresponding to the detected time(S31,S32). The duty rate is increased at the initial stage, and decreased slowly in detecting the large amount of the laundry. The duty rate is decreased at the initial stage, and reduced fast in detecting the small amount of the laundry.
