¿Qué es PWM?
PWM (Pulse Width Modulation) is a digital signaling technique where information is encoded in the duty cycle (ratio of high time to total period) of a rectangular waveform. PWM is universally used in embedded systems for motor speed control, LED brightness dimming, servo positioning, power converter regulation, and DAC emulation. While PWM is not a communication protocol in the traditional sense, analyzing PWM signals is essential for verifying correct duty cycle, frequency, dead time in H-bridge configurations, and timing accuracy. Engineers debugging motor controllers, LED drivers, switching power supplies, and servo systems routinely need to measure PWM parameters and verify that the actual output matches the intended control signal.
