The document discusses various operations that can be performed on signals, including addition, multiplication, time reversal/folding, time shifting, subtraction, and time scaling. It is a lecture on signal operations for a class called PCL 402 - Signals and Systems taught by Prof. Dr. B. Satheesh Monikandan of the Indian Navy. Examples of adding sinusoidal waves to generate a square wave and multiplying signals are provided.
