PURPOSE: To surely maintain output synchronization by relieving the synchronizing condition of digital signals at the input of a switching matrix and that in the propagation of the matrix. CONSTITUTION: A digital matrix 2 has at least two input terminals 6, which receives data signals, at least one output terminal 10, and a means which selectively connects one of the input terminals 6 to the output terminal 10. Each automatic timing circuit 26 has an input terminal connected to the output terminal of a switch and an output terminal. The circuit 26 maintains the frame rate of data signals at the output terminal at a nearly constant level, by propagating data signals to the output terminal by delaying the signals, in response to the data signals at the input terminal. |
