Abstract
The classical optimization criterion used is the signal-to-(quantization) noise ratio (SNR). A general quantization methodology is developed which is based on the optimization of a frequency-weighted SNR: first, a quality criterion based on the weighted SNR is derived from the CCIR (Comite Consultatif International de Radiodiffusion) curves for analog TV: then, a methodology for optimizing the quantization is derived in a general form.Keywords
