Text books leave much to be desired regarding visualization of wave propagation since they are not animated. The package has a sequence of 6 models that have both a transient pulse excitation as well as a sine wave excitation. The model sequence starts with a one transmission line version that has user definable source and load impedance and evolves to a three line model using an exponentially tapered matching section.
<br />Using these models, the student can gain an intuitive understanding of transmission, reflection, superposition, impedance matching, Standing Wave Ratio, and many other wave phenomenons. </p>
<p>This work was inspired by the 1959 Bell Labs film on Waves:

<br />This functions enables converts the signal structures into a power_fftscope format and performs fft analysis.
<br />The function essentially a wrap around of power_fftscope which calculates the magnitude ,phase details of harmonic components of a given signal. Could be handy to analyse the electrical waveforms. (eg voltage, current)
<br />Input method:
<br />fft_list(data,time)
<br />Where data & time are raw matrix in same length.
<br />eg: fft_list(x,t,'f',50)
<br />use help command for more information.
<br />help fft_list</p>
<p>Note: Simpowersystems toolbox is necessary to run this function. Hence the first run might take few seconds to load up, but consequent runs are normal.</p>Rashmil Dahanayakehttp://www.mathworks.com/matlabcentral/profile/authors/4311650-rashmil-dahanayakeMATLAB 8.0 (R2012b)SimPowerSystemsMATLABfalsetag:www.mathworks.com,2005:FileInfo/466272014-05-15T16:48:00Z2014-05-15T20:39:16ZPhasor diagram analyserProgram computes and shows phasor diagram and time graph which is measured in SimPowerSystems.<p>This submission contains block for measuring voltages and currents in your SimPowerSystems model, m-file for computing desired values and gui model for showing phasor diagram.
