#134246 - Resolution does not help you here. Responding to: ???'s previous message |
Then the analog signal will be measured with the 16bit ADC of a cygnal 8051F352
The resolution of the ADC doesn't help you with measuring the duty cycle, since the PWM only has two output values. How precise you are able to determine the duty cycle is determined by the sampling rate. |
