I learned that one way for an ADC to sample its input is using a Sample and Hold circuit.
In order to compute the digital output, the ADC can use a DAC and a comprator, in the following way:
**broken link removed**
Say that the ADC samples a sine wave.
I read that:
1. if i start increasing the sine wave's frequency from zero Hz, then at some point, the output will be a straight line,
2. and that the first frequency that the output becomes a staight line is the ADC's sampling frequency.
What is the reason for these 2 phenomenons?
Thank you.
