PURPOSE:To obtain a display data with a good input following property by using a discrete value at each sampling time to obtain a preset value for the subsequent sampling time. CONSTITUTION:In a case where an input pulse (a) has been inputted to a gate circuit 1, and when a sampling time change-over switch 2-2 is set to a given time, supplied through a switch 2-1 to a counter 3 and computed. The discrete value is latched in a register 4 by a latch signal h, and the discrete value of the counter 3 is cleared. On the other hand, at the leading edge of a change-over signal e, a multiplexer 6 acts such that data of each bit in the register 4 are inputted to input bits that are shifted by one digit, respectively, of the counter 3. During the following prescribed time, the counter 3 adds the counted value of the input pulse to a value of one half obtained previously and supplies the result to a display device 7. As the result, a display effect having a good following characteristic against the action of the input is obtained. |
