Yes Gibbs phenomenon becomes constraining when we are 
analysing signals containing frequency tones quite close to 
each other. If the side lobes of the windowing function are 
significant then it leads to energy leakages between the 
frequency bins/sub-bands. Thus very close lying frenecy 
tones gets their magnitudes smeared up in the process.

take fourier transform

Fourier series is applied for periodic signals since they 
violate Dirchilet's conditions. This will give the 
fundamental and harmonic signal components for periodic 
signals. 

For non-periodic signals if we need frequency analysis as a 
whole then fourier transform is applied for the entire 
duration. Provided its energy is finite and follows other 
conditions as laid out by Dirchilet.


If a finer time resolution is required then short-time 
fourier transform is applied.
