초록정보

An adaptive quantizer for DPCM(differential PCM) is designed, and various performance parameters are compared with the calculated or simulated results. For varieties in experiment, the quantizer is implemented to be a programmable type. Some typical multiplier sets $\{Mi\}=\{\Gamma^{mi}\}$ are simulated for a stationary Gaussion Signal, and the characteristics of $\{mi\}$, $\Gamma$are observed. The performance of the ADPCM coder is checked for real speech signal, where the measured parameters are mean and variance of the quantizer step-size, signal-to-quantizing noise ratio, and signal spectrum. It is shown that the static performance and adaptation speed of the quantizer are strongly affected by $\{mi\}$ and $\Gamma$, respectively. The signal spectrum is observed as an indirect measure for quantizer performance and signal quality.
