[SciPy-user] What's "a sequence"
Wed Apr 11 14:06:54 CDT 2007
I'm trying to design a filter by the Remez exchange algorithm,
but don't know how define "a sequence", like the bands parameter.
From the help:
remez(numtaps, bands, desired, weight=None, Hz=1, type='bandpass',
Calculate the minimax optimal filter using Remez exchange algorithm.
numtaps -- The desired number of taps in the filter.
bands -- A montonic sequence containing the band edges. All elements
must be non-negative and less than 1/2 the sampling frequency
as given by Hz.
I tried several options
i=signal.remez(16, ([0.02,0.06]), ...
i=signal.remez(16, [0.02,0.06], ...
i=signal.remez(16, (0.02,0.06), ...
but they all give an error on the bands-parameter.
