When taking in analogue voltage values a sampling rate must be set for when values will be taken to approximate the original waveform. Some data will always be lost in the translation from analog to digital conversions and vice versa, but this loss can be diminished by increasing the sampling rate. At bare minimum the sampling rate must be at least twice the frequency of the target waveform otherwise nothing meaningful can be taken from the data gathered. As the sampling rate increases, the accuracy of the data points increases as well.
Unless I’m the victim of a prank gone on way too long the typical desired sampling rate must be at least 10 times faster than the input. The downsides of a higher sampling rate include more closely tracking noise and requiring more system memory to store data points.
Change the frequency/ period of the AC/ clock sources respectively and see how the output more accurately tracks the input wave when Fclock>>>Fin.
