A square wave IS a summation of sine waves, in the same sense that 12 is the product of 2*2*3. Yes, there are other ways to describe 12. It’s 10+2, or 36/3, or the square root of 144, among ...

PURPOSETo make a direct comparison between Fourier and Zernike reconstructions of ocular wavefronts using a newly available analytical theory by which Fourier coefficients can be converted to ...

Stationary-wave integrated Fourier-transform spectrometry (SWIFTS)—an approach based on direct intensity detection of a standing wave resulting from either reflection ...

The representation of a PERIODIC sound or WAVEFORM as a sum of Fourier components (i.e. pure SINUSOIDAL WAVEs). According to the FOURIER THEOREM, periodic sound may be shown to consist of SINE WAVEs ...
