When the modulus is reached, the counter goes to 0 on the next clock. The modulus here is a value of 9 and the number of states for the counter is 9+1 or 10. The counting simply repeats for as long as the timer is enabled. how to draw a house to scale

WebApr 11, 2016 · PWM in the Frequency Domain. 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 ...
