What does duty cycle mean in the context of an Arduino Uno? Choose ALL the options that apply Select one or more Oa. The inverse of the period of a rectangular wave (in ms) multiplied by 100 b. The percentage of the period that a rectangular signal is OFF (0 V) c. The ratio given by (ToNTperiod)x100; where TON is the time the signal is ON (5 V) and Tperiod is the duration of one cycle of the rectangular wave. d. The percentage of the period that a rectangular signal is ON (5 V) e. The time that an electrical signal is ON (5 V) Check
