Fourier Transform is actually more “physically real” because any real- world signal MUST have finite energy, and must therefore be aperiodic Fourier Series is applicable only to periodic signals, which has infinite signal energy

In fact, the Fourier transform of the Gaussian function is only real-valued because of the choice of the origin for the t-domain signal If we would shift h(t) in time,

Frequency domain analysis and Fourier transforms are a cornerstone of signal and system analysis. These ideas are also one of the conceptual pillars within.
