Fourier analysis often generates a spectrum with a pattern. Periodic evens can generate a central frequency with some sidebands due to modulation. This tools adds a number of cursors that can be dragged (using the mouse) or can be set to a specific x-locaiton (frequency) by keying in a number in...

For several different reasons it could occur that we need to produce a signal from the sum of several harmonic components. In the usual case of Fourier analysis, FFT and IFFT are likely the best choice. However it could happen that:- The frequencies of the harmonic components are unevenly spaced-...
