What does the microcontroller sampling rate represent?

The sampling rate refers to the number of times the data is read from the ADC and passed along to other application components that use the data.

What is the effect of sampling rate?

It is easy to see the effects of changing the sampling frequency by looking at these transform plots. As the sampling frequency decreases, the signal separation also decreases. When the sampling frequency drops below the Nyquist rate, the frequencies will crossover and cause aliasing.

What happens if sampling rate is inadequate?

We show that inadequate sampling rates may produce inversions in the cause-effect relationship among other artifacts. More generally, slow acquisition rates may distort data interpretation and produce deceptive patterns and eventually leading to misinterpretations, as predators becoming preys.

What happens when sampling rate is too high?

If the rate of samples is too high the system may not be able to process them fast enough - it runs out of processing time.
