ABSTRACT:
An indication of the noise content of data bits on a signal line is derived by sampling the amplitude of a signal on the line several times during each of the data bits to derive for each data bit a several bit binary word. Each bit of the several bit word has a value dependent on the amplitude of the signal on the signal line at the time the sample is taken. In response to the number of binary value transitions in each several bit binary word an indication of the noise content of each data bit is derived.
