Method of switching in a signal selecting system

摘要

A signal selecting system comparator (25) employs a method of switching selected first (40) and second (41) input ports to an output port (43). A block divided first signal (A) is received at the first input (40), buffered and passed to the output (43) as a block divided output signal (E). A block divided second signal (C) is received at the second input. The system waits to the next occurrence of a block boundary in the block divided output signal, identifies that the signal at the second input has priority in routing to the output; and passes the second signal to the output.
