What is the power of a complex signal?
The power of a signal is the sum of the absolute squares of its time-domain samples divided by the signal length, or, equivalently, the square of its RMS level. The function bandpower allows you to estimate signal power in one step.
How do you find the magnitude of a complex number in exponential form?
The exponential form of a complex number is in widespread use in engineering and science. Since z = r(cosθ + isinθ) and since eiθ = cosθ + isinθ we therefore obtain another way in which to denote a complex number: z = reiθ, called the exponential form.
Is exponential signal an energy signal?
"A signal that decays exponentially has finite energy, so, it is also an energy signal."
