The Idea of Orthogonality
Explore the concept of orthogonality in digital signal processing by examining real and complex sinusoids. Understand how orthogonal signals have zero correlation and how this principle applies to frequency components in sampled signals. This lesson helps you grasp a foundational idea critical to analyzing and processing digital signals.

To understand the idea of orthogonality, we consider both real and complex signals.
Real sinusoids
The figure below shows the continuous-time versions of two sinusoids containing samples, one with frequency ...
