FM Demodulation

This is lab 9 of 20 in the course

by Emona Tims

In this lab, students construct a demodulation process that translates the frequency variations of a frequency modulated signal into voltage variation in a linear manner. Students will use the method of zero-crossing detection to translate between signal domains.
