hello guys..
I'm new at python programming and i'm having some problems with a
script that i have been developing for my final project of my
graduation.
I have a script that is supposed to make a plot of a
"Residuo" (waveform) witch is an output of a ADC ( Analogic To Digital
Converter) for the first stage of the Flash pipiline ADC
structure.This script doesn't show any syntax errors but it doesn't
show no waveform at all at the plot window.
I'm worried about this situation so I came here looking for help since
I am new to the Python language.

from pylab import*
Vref = arange(1, 20, 0.02)
Vi = arange(1, 10,0.1)
for i in Vref:
for n in Vi:
if n > i/4:
V0 = 2*n-i
elif (-i/4) <= n and n <= i/4:
V0 = 2*n
elif Vi < -i/4:
V0 = 2*n+i
else:
print "Try Again"
##print V0
plot (V0)boboz10

Only the first 2 'if' conditions are ever true, so nothing is ever
plotted.
Also, I don't know what you're trying to do here:
elif Vi < -i/4:
because Vi is an array and i is a float. If Python ever tried to execute
it there would be a ValueError exception:
ValueError: The truth value of an array with more than one element is
ambiguous.
Use a.any() or a.all()
