Abstract

PURPOSE:To constitute an interleaving circuit with N pieces of flip-flops to N digits, by using N-1 pieces of selectors plus two dividers. CONSTITUTION:N-1 pieces of selectors 60a-60h plus dividers 90 and 100 are used to N-1 units of flip-flops 70a-70i. When a logic level ''0'' is applied to a control terminal SEL of these selectors, the signal at the side of the input terminal A of the selectors is delvered to an output terminal X. When a logic level ''1'' is applied to the SEL, the signal at the side of the input terminal B of the selectors is delivered to the terminal X. When an output signal line 1,000 of the divider 100 is at logic ''0'', the side of terminal A of the selectors is selected. Then FF70a-FF70i forms a shift register in which a connection is carried out in the order of 70a-70b-70c-70d- 70e-70f-70g-70h-70i (mode A). When the line 1,000 is at logic level ''1'', the side of terminal B of the selectors is selected. Then FF70a-70i forms a shift register in which a connection is given in the order of 70a-70d-70g-70b-70e-70c-70f-70i (mode B). When the time series (1, 2, 3, 4, 5, 6, 7, 8, 9) written in the mode A is read in the mode B, the time series is converted into the one (1, 4, 7, 2, 5, 8, 3, 6, 9).
