Question

How is 25% duty cycle PWM signl represented in waveforms? a) High for 25% of the total period, low for 75%

b) Low for 25% of the total period, high for 75%
c) High for 75% of the total period, low for 25%
d) Low for 75% of the total period, high for 25%

Answer 1

A 25% duty cycle PWM signal is represented by the waveform being high for 25% of the total period and low for 75%.

Step-by-step explanation:

A duty cycle refers to the percentage of time something is "active". In the case of a PWM (Pulse Width Modulation) signal, the duty cycle represents the percentage of time the signal is in the "on" state compared to the total period of the signal.

For a 25% duty cycle PWM signal, the signal is high for 25% of the total period and low for 75% of the total period. This means that the signal spends more time in the "low" state than in the "high" state. Therefore, the correct representation of a 25% duty cycle PWM signal in waveforms is option a) High for 25% of the total period, low for 75%.
