Abstract: PURPOSE: A method for checking a vocoder capable of measuring sound quality in a communication system is provided to generate a regularly-patternized signal in the vocoder to compare the patternized signal with an original signal via compressing/restoring processes, so as to perceive sound deteriorations. CONSTITUTION: A digital signal processor(DSP) accepts a vocoder inner packet loopback command from a selector, and analyzes the accepted command. If the accepted command is an inner packet loopback command, the DSP performs an inner packet loopback operation. If the command from the selector is an algorithm test command, the DSP generates a cosine. The DSP stands by for one second not to generate an error. The DSP calculates a frequency and energy of encoded/decoded pulse code modulation(PCM) data in a part corresponding to the one second. The DSP sets up a 'ready' variable as 1, and stores the calculated frequency and the energy in a memory. The DSP transmits information on the calculated frequency and the energy to the selector. A 'Get' algorithm command is performed in the selector. A vocoder receiving the 'Get' algorithm command transmits the calculated frequency and the energy to the selector.
