Foundations of Random Processes and Stochastic Systems

Analyzing systems with inherent uncertainty requires more than basic probability; it demands a solid grasp of how random variables evolve over time. This text-based course guides you through the core mathematical framework of random processes, equipping you to model noise, predict system behavior, and analyze stochastic systems. Through this course, you will: 1. Understand foundational probability concepts, joint distributions, and expectation. 2. Define and classify random processes, including stationary and ergodic processes. 3. Analyze spectral density, autocorrelation, and cross-correlation functions. 4. Apply Markov chains and random walks to model step-by-step state transitions. 5. Evaluate how random signals pass through linear time-invariant systems. 6. Practice solving analytical problems through detailed, step-by-step written exercises. You will start with essential definitions of probability and random variables before moving into time-varying stochastic behavior, spectral analysis, and modern applications in signal processing. This course is designed for engineering students, data analysts, and beginners looking for a clear, structured introduction to stochastic mathematics without complex prerequisites.
