A message is composed of signal characters. A character is an element in a mutually agreed finite set of different information elements. Process signals possess a very simple information content because they have a specifically simple character set. 4. 4 The character set of analog and digital signals Signal Character set Example* Timecontinuous analog signal Binary numbers 8, 10 or 12 bits withfwithout sign 00110110 = 54 Timediscrete analog signal Binary numbers 8,10 or 12 bits interrupted by a row of 'out of range' characters Binary digital signal o or 1 in aseries Counter state digital signal Binary or binary coded decimal numbers; up to ten decades Count digital signal Binary states 0 or 1 in aseries.
