FilterBank¶

class acoular.tprocess.FilterBank¶

Bases: TimeInOut

Abstract base class for IIR filter banks based on scipy lfilter implements a bank of parallel filters

Should not be instanciated by itself

sos = Property()¶

List of filter coefficients for all filters

bands = Property()¶

List of labels for bands

numbands = Property()¶

Number of bands

numchannels = Property()¶

Number of bands

result(num)¶

Python generator that yields the output block-wise.

Parameters:

numinteger

This parameter defines the size of the blocks to be yielded (i.e. the number of samples per block).

Returns:

Samples in blocks of shape (num, numchannels).

Delivers the bandpass filtered output of source. The last block may be shorter than num.
