Examples of Sampled Signals

Sampling and Reconstruction

This is lab 14 of 20 in the course

by Emona Tims

Students will explore how analog signals are converted to digital signals for use with digital transmissions systems. Students will sample a message using sample-and-hold scheme, examine the message in the frequency domain, reconstruct the message, as well as explore the relationship between sampling frequency and aliasing.
