% VTB7%% VTB7_1 is an example of taking a power spectral density% of data. The power spectral density of a signal% containing .5 Hz and 1.59 Hz signals is plotted.% VTB7_2 generates the discrete frequency response% function (H(iw)) between two signals.% VTB7_3 A set of files numbered from VTB7_3_1.mat to% VTB7_3_6.mat exist which contain discrete frequency% response functions. After loading the data,% plot(FreqV,abs(Xfer)) will give the magnitude% and plot(FreqV,angle(Xfer)) will give the phase% plot. Note the differences between experimental% data and what you would expect from theory.
