WebApr 11, 2016 · In the previous article we saw that a pulse-width-modulated signal can be “smoothed” into a fairly stable voltage ranging from ground to logic high (e.g., 3.3 V); the smoothing is accomplished by a simple low-pass filter. Thus, we can achieve digital-to-analog conversion by using firmware or hardware to vary the PWM duty cycle according … WebJul 23, 2024 · Procedure First-Order Low-Pass Filter: With a first order low-pass filter built, the lab can begin.
