Abstract
There is provided a digital time base corrector in which a digital input signal of one block consisting of a continuous data time sequence is converted to a digital signal including data lack intervals or vice versa by a variable delay circuit. A signal selecting circuit is divided into N first unit selecting circuits and a second unit selecting circuit. M of the output signals of a shift register are inputted to the first unit selecting circuits, by which one of them is selected. The outputs of the N first unit selecting circuits are supplied to the second unit selecting circuit, by which one of them is selected. A pipeline process is performed by inserting a delay circuit to delay the signal for the time of one clock period into the input/output line of the second unit selecting circuit. Further, the selecting signal can be made variable for every one clock and a delay circuit is inserted on the output side of a selecting signal forming circuit. With this corrector, the influence of the gate delay of the selectors can be reduced and the high speed data process can be performed.
