The Signal Processing Foundations series of 16 lessons begins with the philosophy of the field. Next you will discover the basic notation and terminology. Signal Processing Foundations also introduces methods for describing the interaction between signals and signal-processing systems. Understanding the philosophy of signal processing will help you later follow the context and rationale for different signal processing methods. Signal processing has developed its own language for clearly communicating important concepts; Signal Processing Foundations will teach you cornerstone vocabulary of the field. You will also be introduced to several mathematical tools for relating the input to the output of signal-processing systems. Different tools provide different perspectives on the interaction and have different roles in signal processing.
