On the Interference of Pulse Trains

A number of problems arising from the undesired overlapping or time coincidence of pulses from separate periodic pulse trains are considered. The coincidence time fraction is determined for two pulse trains with both a fixed initial phase and a randomly varying initial phase. The coincidence time fraction for these cases is then determined if only pulse coincidences equaling or exceeding a specified interval are considered. Finally, some problems involving more than two pulse trains are briefly discussed.
