Signals with Multiple Frequencies (Week 14 - Day 28)

     In this lab, we compared different frequencies in our circuit. We used a custom mathematical function as our input voltage and then measured the output voltage across the second resistor (as seen below) which was in parallel with our capacitor.

     Below are screenshots of the data our Analog Discovery retrieved from our circuit setup.  

     These waves represent the voltage gain of the input function from our first resistor and the output as seen by the orange cables in the figure above.
