What is Signal?
- A signal may be considered as an interruption in a field of constant energy transfer.
- Example: Electromagnetic field of a telegraph circuit, voice signal, video signal.
What is System?
- System is a device or combination of devices. system is a system which describes the information exchange between two points. A system is any process that produces an output signal in response to an input signal.
- Example: Communication System ( transmitter, receiver)
