What are the basic signals?


What are the basic signals? The step, ramp, impulse, exponential, and sinusoidal functions, etc., are the basic signals. These signals may be combined by addition or subtraction to build a variety of general waveforms used in practice. Signals play an important role in life. They are used in communication, speech processing, medical science, etc.


What are the 5 basic signals?

Signals Basic Types
  • Unit step function is denoted by u(t). It is defined as u(t) = {1t?00t<0.
  • Impulse function is denoted by d(t). ...
  • Ramp signal is denoted by r(t), and it is defined as r(t) = {tt?00t<0.
  • Parabolic signal can be defined as x(t) = {t2/2t?00t<0.
  • Signum function is denoted as sgn(t).
