Introduction to Signal and System

A Signal is a term used to mean the data conveying property being communicated to or from an element, for example, a sent to or from an element, for example, a gadget, instrument, or physiological source


  • Radio and Television Signals
  • Telecommunications and Computer Signals
  • Biomedical Engineering Signals

Signals are related with autonomous Signals are related with a free variable(s): e.g., time, single or multivariate spatial arrange

  • Most instrumentation signals have time as their free factor
  • A computerized photo or picture has spatial directions as its autonomous factors

We can likewise speak to a Signal by a waveform we can likewise speak to a Signal by a waveform

  • Signal Independent Variables can be all things considered
  • Nonstop (likewise called Analog) or Discrete

A System is a term used to mean an element that measure or works on Signal(s) to change one sign to another

  • Manipulate
  • Change
  • Record
  • Transmit

A System has information sources and yields

  • Amplifiers, Radios, Televisions
  • Telephone, Modem, Computer

Oscilloscopes ECG EEG EMG

FAQ’s on Signal and System Notes

Question 1.
Define Continuous-time Signal?

A continuous-time signal is a quantity of interest that depends on an independent variable, where we usually think of the independent variable as time. Two examples are the voltage at a particular node in an electrical circuit and the room temperature at a particular spot, both as functions of time.

Question 2.
Define Signal?

In electronics, a signal is an electric current or electromagnetic field used to convey data from one place to another. The simplest form of signal is a direct current (DC).

Question 3.
What Are The Major Classifications Of The Signal?


  • Discrete signal
  • continuous signal
  • Noncontinuous signal
  • periodic signal
  • Non-periodic signal.

Question 4.
State Properties of Convolution?

Commutative, associative, distributive, shifting property etc.
