Filed: 1986-06-03
Abstract: PURPOSE:To obtain a timing circuit with a high resolution by providing a shift matrix, a shift register with few stages, a delay circuit and the like. CONSTITUTION:The output clock of a clock generator 1 is divided to an eighth by a divider 2 to form a sampling pulse 29. The output of the divider 2 is further divided to form an optical pulse repetitive signal 9. The signals 9 are generated at equal intervals and supplied to the data input of a shift register 11. Driving the register 11 by the clocks of the generator 1 produces output signals. The output signals are supplied to a data selector 12 which selects one wave of the output signals under the output condition of a shift matrix 16. The output of the selector 12 is inputted to another data selector 14 via a delay circuit 13. Only one wave is taken out of the output signals of the selector 14 as an optical pulse timing signal 28 due to the output condition of the matrix 16 in the same fashion as in case of the selector 12. Thus, a circuit with a high resolution can be obtained by a simple structure.
