Calculating the Energy and Power of the Signals
The Energy of the Signals can be calculated as
Square of amplitude/magnitude(if complex) over entire time domain.
for a continuous time signal
for a discrete time signal
The power of the Signal can be calculated as
Rate of change of energy.
for a continuous time signal.
for a discrete time signal-
Classes of signals on the basis of their power and energy
- Energy signal: generally converging signals, aperiodic signals or signals that are bounded.
- Power signal: generally periodic signals, as they encompass infinite area under their graph and extend from to .
- Neither energy nor power signal
Introduction to Signals and Systems: Properties of systems
In this article, we will go through Signal and systems, First, we will define what is a signal and what is a system, then we will go through the calculation of the Energy and Power of Signals with their transformation, At last we will conclude our article with Properties, Applications and some FAQs.
