Unmasking I/Q Signals: The Mystery of Wireless Communication

This article unveils the mystery behind I/Q signals, crucial in wireless communication but absent in traditional audio processing. It delves into the relationship between I/Q signals, sinusoidal waves, and the Fourier Transform. Using vector mathematics and the dot product, the article explains the orthogonality of I/Q signals and how they enable efficient modulation and demodulation. Finally, it clarifies why complex numbers are a more efficient way to represent I/Q signals in digital signal processing.
