About the Signal Processing with AI Website

This website is designed as a proof-of-concept site to help both instructors and students who are interested in learning about how AI can be used to teach signal processing.

Warning

This is not a complete course on signal processing. It is a course that helps instructors and students learn how to use generative AI tools to create content in a signal processing course.

This website uses generative AI to create content around a learning graph and encourages both instructors and students to use generative AI to create and modify content such as simulations and animations of signal processing concepts.

We have used the following workflow to generate much of this website.

What is Signal Processing?

Signal Processing is the analysis, manipulation, and interpretation of signals to extract meaningful information, enhance signal quality, or transform signals into more useful forms.

Core Definition

Signal processing involves mathematical and computational techniques applied to time-varying data (signals) such as audio, video, sensor measurements, or communication data. The field encompasses both analog and digital methods for filtering, amplifying, modulating, compressing, and analyzing signals to achieve specific objectives like noise reduction, feature extraction, or data compression.

Key Characteristics

Input: Raw signals from various sources (microphones, cameras, sensors, antennas)

Processing: Mathematical operations including filtering, transformation, correlation, and statistical analysis

Output: Enhanced, modified, or analyzed signals that serve specific applications

Fundamental Applications

Signal processing is essential in telecommunications, audio/video systems, medical imaging, radar, control systems, and data analysis. Common operations include removing unwanted noise from audio recordings, compressing images for storage, extracting features from sensor data, and converting analog signals to digital format for computer processing.

Mathematical Foundation

The discipline relies heavily on concepts from linear algebra, calculus, probability theory, and Fourier analysis to represent signals in different domains (time, frequency, spatial) and apply appropriate transformations to achieve desired results.
