Does the definition of duty cycle indicate only the percentage of time that the level is asserted? For example, if a 10 Hz square wave is de-asserted for 5 of those 10Hz cycles and asserted for 5 of the 10Hz cycles, would that represent a 50% duty cycle? If I represent each of the de-asserted 10 Hz cycles in a single second as a 0 and each of the asserted 10 Hz cycles in that same second as a 1, I could represent a 50% duty cycle as 0000011111. But if it is only the percentage that matters, I could also get 50% by the sequence 0101010101. In the definition of duty cycle, is it necessarily the case that the asserted periods be consecutive and that the de-asserted periods also be consecutive?
