Lab 8 - Visualization

Pre Lab requirments

Install bokeh via pip or via the full anaconda distribuition
Install nova instrumentation

Starting steps

Test simple graph on ipython notebook

Lab Goals

Goal 1 - Transfer function of a low pass

Plot the DB of the transfer function of the gain in a frequency log scale. ** |H| = 1/sqrt(1 + (f/f_c)^2)
Plot the phase of the transfer function in degrees in a frequency log scale. ** phase(H) = -2 arctan(f/f_c)$

Goal 2 - Random walk

Plot a random walk (1000 samples)
Plot the mean sliding window (using ni.smooth, with 50 samples window).
Plot the variance band.
Draw multiples superimposed random walks.

Goal 3 - XY Graph

Draw a xy graph of a sin(w) and cos(2w)
Adjust the axis to be a square figure
Place 9 lissajous figures in subplots

Goal 4 - Matrix images

Create a matrix of zeros and draw a circle by turning some points to 1
Smooth the image with a vertical smooth by passing in each column.
Smooth the image with a vertical smooth and horizontal pass.
