• Signal: Pattern of variations of a physical quantity that carries information and that can be manipulated, stored or transmitted by physical processes
• System: Something that can manipulate, store or transmit signals
Signals & Systems
• Signal: A function of one or more variables that conveys information on the nature of a physical phenomenon
• System: An entity that manipulates one or more signals to accomplish a function, thereby yielding new signals
Signals & Systems
• Signal: Function of one or more independent variable, contains information about the behavior or nature of some phenomenon
• System: Responds to a signal particular signal by producing other signals or some desired behavior
