Реферат: A parity determining circuit is used to determine the parity of a binary word. The binary word is represented by a sequence of optical bit slots. Each bit slot defines a respective one of two complementary logical states. The circuit includes: an input pulse stream generator that generates copies of the binary word; a combining device that receives two binary words, offsets one word with respect to the other, and then combines them to form a combination word; and a circuit that applies a copy of the original binary word together with the combination word to the combining device a number of times in succession. This results in a combination word that has a number of bits in the same logical state and that indicates the parity of the binary word.
