Fourier Transform and Fourier series both transform time domain expressions into the frequency domain. Fourier series transforms periodic waveforms into a series of spectral lines separated by frequency intervals, while Fourier Transform transforms non-periodic waveforms into a continuous spectral distribution across all frequencies rather than just harmonics.

- 2. Fourier series transforms the time domain expression for a continuous periodic waveform into frequency domain of which pictures a series of spectral lines separated by equal intervals of frequency and of different amplitude and phase. Fourier Transform is a similar process whereby a time domain non-periodic waveform is transformed into a frequency domain (and vice-versa) which leads to continuous spectral distribution at all frequencies ( not just harmonics).
