Abstract: A parallel to sequential message converter including a pair of signal terminals for receiving a first input signal having a duration of a first time period and a second input signal having a duration of a second time period which is less than the first time period, and wherein the second input signal is received concurrently with a portion of the first input signal so that a time overlap in signals exists. The first input signal is delayed at the onset of the second input signal for a period substantially equal to the time period of the second input signal. The second input signal is inserted into the signal stream at the start thereof and the delayed first input signal is thereafter reinserted so as to provide a sequential output of the first and the second input signals at an output terminal without a loss of any portion of the first input signal.
