Joseph, you are absolutely right. My question is 'is there any easy way of converting the pwm duty cyle in to an analog signal precisly?' No. You have already said you are interested in low duty cycles. This means you will be "closer" to the noise, and your uncertainty will rise. For something quick and dirty, an integrator and your ADC will be an indicator, but you will be fooling yourself about "16bits" of resolution, if your precision is 7 bits. Steve |
