Fourier Series
An alterna/ve but equivalent representa/on for /me varying signals is in
the frequency (Fourier) domain.
Why frequency domain? Frequency domain representa/ons simplies the
analysis and design of LTI syste

Fourier Transform
Fourier series (FS) allows us to represent periodic signal in terms of
sinusoidal or exponen9als ejkot.
Fourier transform (FT) allows us to represent aperiodic (not periodic)
signal in terms of expon

Systems
System: processes an input signal producing an output signal with certain
features of the input signal enhanced and other features unchanged or
diminished.
