PROBLEM TO BE SOLVED: To eliminate a disturbing edge from a digital signal. SOLUTION: A controller for switches 1-4 generates a 1st control pulse, whose specific duration time is Δt1 , on occurrence of a 1st edge of a signal given to an output terminal of buffers 9, 10 and generates a 2nd control pulse, whose specific duration time is Δt2 , on occurrence of a 2nd edge. In this case, the 1st control pulse switches the 1st switch 1 from on a off state and the 4th switch 4 from an off state to an on state, and the 2nd control pulse switches the 2nd switch 2 from an on to off state and the 3rd switch 3 from an off state to an state. |
