fftlen
(the length of your FFT) in the FFT block. How do I unscale or remove the scaling factor in the python generated by thr GRC? I tried the one suggested in the faq,... forward FFT --> multiply_const_cc(fftlen*[1.0/fftlen,]) --> reverse FFT ...
but it doesn't seem to work. I know I am missing something. How do I insert this into this line of code in my python?
1. self.fft_vxx_0 = fft.fft_vcc(1024, True, (window.rectangular(1024)), True, 1)
or here?
2. self.blocks_complex_to_mag_squared_0 = blocks.complex_to_mag_squared(1024)
Thank you in advance.
Attached is my flow graph.
