In the traditional dynamic delay generation method,the delay accuracy is difficult to increase and the wideband is very narrow.In this paper,a high-precision and wideband method is proposed.This method uses the VFD filter to achieve the fractional delay,through the Farrow structure the delay can be changed on line.The simulation shows that when the filter order is 50,the 0.01 sampling delayaccuracy can be achieved in ± 0.9π bandwidth.
