Hi All, I am doing simple wide band FM..The flowgraph is as attached..When i execute it i am getting following error:
gr_remez: insufficient extremals -- cannot continue
Traceback (most recent call last):
File "/home/ali/Desktop/top_block.py", line 109, in <module>

line 466, in pm_remez
return _filter_swig.pm_remez(*args, **kwargs)
RuntimeError: gr_remez: insufficient extremals -- cannot continue
Is the quadrature rate and audio rate are high?
