4 Demonstrate Noise Suppression

The noise suppression is demonstrated by using example source code and plotting a graph of ADC samples in the Data Visualizer.

A signal with noise is given as an input signal to the ADC. It will be sampled and the ADC result value is sent over EUSART to the serial terminal of the Data Visualizer, and a graph of the ADC samples is plotted in the Data Visualizer. Different graphs with different computation modes such as Basic mode, Accumulate mode, Average mode, Burst Average mode, and Low Pass Filter mode are plotted. From these graphs, it can be observed how the ADC result count range gets reduced when noise is suppressed in the configured computation mode. A detailed explanation is provided in the further sections.
