			In ''Logic World'', the simulation runs at a adjustable ''Tick Rate'' (number of ticks per second).
			Since period is measured in ticks, the real-time frequency can be calculated as:

			::<math>f_{Hz} = \frac{\text{Tick Rate}}{\text{Period}}</math>

			For example, with a tick rate of 60 and a clock period of 12 ticks:

			::<math>f_{Hz} = \frac{60}{12} = 5\ \text{Hz}</math>

			Increasing the tick rate or reducing the clock period increases frequency.
