PURPOSE:To enable to vary the delay time acceleratingly, by using the oscillator of which frequency is changed with the control voltage and changing this control voltage with time. CONSTITUTION:The voltage generator 6 gives the voltage increased in proportion to time to the voltage controlled oscillator 1' to produce the pulse signal in which the oscillation frequency is gradually increased. This pulse signal is given to the conter 2, which counts it and introduces the count output to each digit 1,2,...,n. The delay circuits 31, 32,...,3n forming the delay circuit group 3 are active in response to this count output, making delay the delayed signal which is inputted by the weighted time T,2T,...,2<2-1>T set to the delay circuits 31,32,...,3n. |
