TFSA PLOTTING FACILITIES Plotting routines used to visualise data. The following types of graphs can be employed: (i) Plot (ii) Image (iii) Pseudo-Colour (iv) Waterfall (1 and 2) (v) TFSAPL (vi) TFSAPLL EXPLANATION OF VARIOUS PLOTTING ROUTINES (i) Plot Used for one dimensional plots of signals, IF estimation, wavelet coefficients, frequency spectra etc. (ii) Image Used to plot two dimensional matrices such as time-frequency distributions and scalograms. Displays the matrix as an image. (iii) Pseudo-Colour Pseudo-colour plots a colour grid for each element of the input matrix. Also used to plot two dimensional matrices such as time-frequency distributions and scalograms. (iv) Waterfall 1 and 2 Again also used to plot two dimensional matrices such as time-frequency distributions and scalograms. This uses a waterfall style plot of the matrix, using different viewing angles which distinguish Waterfall 1 and Waterfall 2. (v) TFSAL Used to display the time-frequency distribution matrix over the time-frequency plane. Subplots of the time domain signal and the power spectrum are provided along the axises of the time-frequency plot. (vi) TFSAPLL Equivalent to TFSAPL except the log of the time-frequency distribution is plotted.
