hello,I'm using a FIR filter and I have the error : "Param - Taps(taps): Expression None is invalid for type'complex_vector'."
my taps is : firdes.low_pass ( 1, samp_rate, frec_carrier, 25000,firdes.WIN_HAMMING )
samp_rate and frec_carrier are both variables in my graph.I don't understand why I have an error. Please could you tell me what I am doing wrong?
Thank you.
