Lab 2: Active and Passive Filters

Active Low-Pass Filter Circuit Connected to Analog Discovery 2
This lab introduces students to the basic terminology and characteristics of filters such as filter slope, passband, stopband, and cut-off frequency. Students will learn about filter transfer functions for passive and active filters as well as higher-order passive filters and apply their knowledge by simulating and building these circuits. Advanced students can challenge themselves by exploring higher-order active filter implementations (such as Chebyshev and Butterworth) and how these implementations maximize different filter characteristics.
