Vector_source_c takes in an argument numb which is a list that contains fft_size values. I will paste the qa code here(http://pastebin.com/da21Ww4B).

Something a little bit out of topic:

Part of your code at http://pastebin.com/da21Ww4B

        numb=list()

        for i in range (n):

                numb.append(complex(lst1[i],lst2[i]))

Above code is not "vectorized".

The vectorized version may look like:

        numb = numpy.complex64( lst1 )  +  1j * numpy.complex64( lst2 )

Vectorization is probably less critical in unittest, but should not be overlooked for blocked coded in python.
