A probability distribution analyser for TV signals
Abstract
A signal analyzer is described which measures the probability distribution function of digital video signals and displays it on an oscilloscope. Experiments conducted to compare the performance of two different predictors for use in a differential pulse code modulation coder are considered. The use of the analyzer in conjunction with video noise reduction equipment to measure the noise power in a stationary picture is also reported.
