Symmetry Properties

Observe the symmetry characteristics of an input signal and figure out the corresponding spectrum.

We now observe a few symmetry properties of the Fourier transform without mathematical derivations. This is important because it helps us gain some mastery over the signal behavior and intuitively notice an error in signal processing output.

Real and even signal

To understand the symmetry in the transform of a real and even signal (i.e., a signal that has symmetric values around 00 ...
