Understanding the lowpass filtering of a digital signal

WebJun 29, 2024 · Low-pass filters always transition smoothly from the passband to the stopband. Furthermore, there is nothing magical about the “cutoff” frequency, which is more accurately referred to as the –3dB frequency, i.e., the frequency at which the magnitude response is 3 dB lower than the value at 0 Hz. It seems to me that this is the primary ... 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 …
