Intro to Sampling Theory

Wiring diagram for loopback test
Learn what sample rate means and how Nyquist’s theorem affects your data. Students perform a loopback test with a sine wave they generate. By adjusting the sampling rate and observing how this affects the acquired signal they learn about aliasing and the importance of selecting the correct sampling rate for an application. This project also introduces programming through a pre-built Virtual Instrument.
This is module 2 of 10 in the course set, myDAQ Projects for Engineering Students.
