In Mixed signal applications we must consider the operating bandwidth. The most visual representation of this behavior is obtained by a bode diagram, stimulating the system with a known fundamental signal to compare and measure the magnitude and phase in the output. For academic purposes, the most widely used platform is the Arduino, with boards based on the AVR microcontroller.

This talk will investigate the software and hardware tools required to implement a basic mixed-signal system, bringing a better understanding of frequency system response using a microcontroller and Analog filters. You will be able to implement an experiment to facilitate your own learning system.
