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. The reference signal can come from a local oscillator.

What are the classifications of signals?
Today we will learn about the types of signals. Start with the following. Signals are classified into the following categories: Continuous Time and Discrete Time Signals Deterministic and Non-deterministic Signals Even and Odd Signals Periodic and Aperiodic Signals Energy and Power Signals Real and Imaginary Signals Continuous Time and Discrete Time Signals A signal is [...]
