Good morning Martin,
please can you explain to me what you mean by REPL?
Thank you have a good day
Can you try running this in a REPL to see what the return value of firdes.lowpass(...) is?

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.
