How do you find the real and imaginary part of a signal?
In signal processing "real" denotes a signal component that is in phase with (i.e. has a 0° phase shift from) some reference signal. Imaginary denotes a signal component that is in quadrature with (i.e. has a 90° phase shift from) the same reference signal.
What is real and complex signal?
A real signal at any given time takes its value in the set of real numbers, and a complex signal takes its value in the set of complex numbers.
How do you find 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.
