Abstract:

The article begins with a discussion of noises which appear during the transmission of information through analog-modulation and pulse-code-modulation. Subsequently, only those noises are analyzed which are produced during the analog-to-digital conversion and which impose a limitation on the channel capacity depending on the quality of the decision stages in the circuit. First amplitude quantization is considered in general, next the errors due to vaccilating decision levels. The probability density of the quantization error is calculated and plotted as a distribution function the quantization noise power in the case of vaccilating decision levels is determined and finally, three possible sources of error in a practically designed ADC.
