Yes, that's correct. Both Fourier Series and Fourier Transform are based on the same mathematical ideas of representing a signal as a sum of sinusoidal components, but they serve different purposes. Fourier Series is used to represent periodic signals with a finite duration, while Fourier Transform is used to analyze continuous signals in the frequency domain. The key difference is that Fourier Series decomposes a signal into a sum of discrete frequencies, while Fourier Transform represents the same signal as a continuous spectrum over a range of frequencies.
