[Discuss-gnuradio] Signal Multiplication

[Jonathan Shan]

Hello all,

I am new to gnuradio and communication theory.

I am trying to multiply two signals by their corresponding elements. I am 
trying to mimic amplitude modulation.

I already have source1 which is a sine wave generated by sig_source_c. 
There is source2, which is a vector source generated by vector_source_c. I 
can confirm that both these sources are "correct" individually, but when I 
try to multiply them by doing multiply_cc, weird stuff happens.

Example is if I set the vector to all zeroes, I expect the output of 
multiplier to be all zeroes. This is not the case.

Thanks,
Jonathan
