There are two varieties of square waveforms that can be described by Fourier series, one being odd and the other even. Figure 10.8 illustrates the two waveforms with expression 10.19 giving the Fourier representation of the odd square wave and expression 10.20 giving the representation for the even...
Tags Fourier Fourier series Norm Series Space Replies: 26 Forum: Calculus and Beyond Homework Help S Fourier transform of wave packet I am unsure if ##h(x,t)## really is a wave packet, but it looks like one, hence the title. Anyway, so I'd like to determine ##\hat{h}(k,t...
[Limpkin]’s current project uses the same module to create a Doppler speed sensor, but with a little more sophistication all around. Whereas the original used a simple comparator to output a square wave that’s proportional to the Doppler shift and displayed the speed on a simple terminal ...
Sawtooth waves have come up several times here. For one thing, they have rich harmonics. Because the wave form is discontinuous, the Fourier coefficients decay to zero slowly. I wrote about thathere. The post is about square waves and triangular waves, but sawtooth waves are very similar. He...

The FT analysis of LSI data starts by computing the power spectral density. We perform the FFT on a time sequence ofNspeckle patterns, whereNis a power of 2 for computational efficiency. Each (xyt)-voxel is treated as an intensity time series of lengthN; all voxels are transformed simultaneo...

Electroretinography (ERG) is a non-invasive method of assessing retinal function by recording the retina’s response to a brief flash of light. This study focused on optimizing the ERG waveform signal classification by utilizing Short-Time Fourier Transf
