WebJan 8, 2024 · The PWM duty cycle refers to the “on” state versus the “off” state. If we see high pulses for 50% of the time, we have a 50% duty cycle. Use the duty cycles of a PWM circuit to help determine resistance and capacitance values. Driving a cooling fan motor with PWM causes the motor to respond to the average of the pulses. WebPulse skew (tsk(p)) is the magnitude of the time difference between the high-to-low (tPHL)andthe low-to-high (tPLH) propagation delays when a single switching input causes one or more outputs to switch, tsk(p) =tPHL −tPLH . Pulse skew is sometimes referred to as pulse width distortion or duty cycle skew. INPUT OUTPUT 1 OUTPUT 2 OUTPUT n ...
