What is Signal?

  • 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)
