Spurious pulses can be generated on wired-OR computer bus lines under certain conditions. The letter explains how they are caused and presents two methods for overcoming their effects. The first relies on timing within the devices connected to the bus; the second, thought to be preferable, involves forming the line into a loop and arranging for each device to sense the signal at two points along it.
