Testing with more samples ( now 1024, before 128)

Plots



In [5]:

    
fig = plt.figure()
for i in range (0, 40):
    functions.ErrorPlotWave(i, 127,1024)

With more samples the error rate at wave number 16 and 32 is no longer lower then expected.



In [7]:

    
fig = plt.figure(1, figsize=(15, 3))
functions.medianSinPlot(15, 127)
plt.title('Wave number 15')
fig = plt.figure(2, figsize=(15, 3)) 
functions.medianSinPlot(16, 127)
plt.title('Wave number 16')
fig = plt.figure(3, figsize=(15, 3)) 
functions.medianSinPlot(17, 127)
plt.title('Wave number 17')
