ECE538 Week 9:
The purpose of this week is to understand digital subbanding and single-sideband modulation.
Digital Signal Processing
Largely based on Purdue University’s ECE538, Fall 2025, taught by Dr. Mike Zoltowski
ECE538 Week 8: Reconstruction Process and Upsampling
ECE538 Week 7: Sampling Theory Basics
The purpose of this week is to derive the relationship between the CTFT and DTFT, thus dipping our toes into sampling theory.
$$\boxed{X_s(\omega F_s) = X(\omega)}$$
ECE538 Week 6: CTFT and D/A Conversion
The purpose of this week is to revisit the continuous time fourier transform (CTFT) to prepare to understand sampling theory and digital to analog (D/A) conversion.
