Editing Analytic signal (section)

===The monogenic signal===
The real and imaginary parts of the analytic signal correspond to the two elements of the vector-valued [[monogenic signal]], as it is defined for one-variable signals. However, the monogenic signal can be extended to arbitrary number of variables in a straightforward manner, producing an {{nowrap|(''n'' + 1)}}-dimensional vector-valued function for the case of ''n''-variable signals.
