Sampling rate conversion is, in general, implemented using time domain based poly-phase filter structures. The other way of implementing multi-rate signal processing is frequency domain based approach, which has the advantage of computational savings. This paper clearly explains how to apply frequency...

value. Since the duration of these rectangle pulses is finite, Ts> 0, this results in an output spectrum. In the frequency domain, this output spectrum is described with the sinx/x function. The sinx/x function, which is also known as a sinc function, has zeros at the frequency fs= 1...
SUMMARYThe computational efficiency of 2.5-D seismic wave modelling in the frequency domain depends largely on the wavenumber sampling strategy used. This involves determining the wavenumber range and the number of the sampling points, and overcoming the singularities in the wavenumber spectrum when takin...

Various techniques exist for measuring the structure of a plasma wake13. The electron density distribution can be imaged using laser-based methods like shadowgraphy14and frequency domain holography15. Also the magnetic fields inside the wake can be measured using lasers via the Faraday effect16,17....
