filter: adding rational resampler with GRC and QA.
e5aead88 06/19/2012 04:07 am Tom Rondeau

filter: adding PFB arbitrary resampler (ccf and fff) with GRC and QA.
5365daf7 06/18/2012 07:42 pm Tom Rondeau

filter: adding PFB interpolator with GRC and QA.
622464a3 06/18/2012 06:37 pm Tom Rondeau

filter: adding PFB decimator with GRC and QA.
f5449ce2 06/18/2012 05:34 pm Tom Rondeau

filter: added interp_fir_filter with QA and GRC.
f049a184 06/18/2012 01:49 am Tom Rondeau

filter: adding fractional_interpolator_{cc,ff} with QA and GRC.
ce3d887a 06/17/2012 08:44 pm Tom Rondeau

filter: added mmse_fir_interpolator with QA code.
d647fbba 06/16/2012 02:55 pm Tom Rondeau

filter: adding freq_xlating_filter.

Includes QA and GRC.

Update to build_utils adds a FIR_TYPE for the type of filter and CFIR_TYPE for the type of filter where the taps are always complex (needed for freq_xlating_filter).
3cd0ea45 06/15/2012 09:56 pm Tom Rondeau

filter: adding IIR filter.

Include QA and GRC.
b70bcc34 06/15/2012 08:34 pm Tom Rondeau

filter: copied over interpolator_taps.h to gr-filter.
76a6a4c6 06/15/2012 08:05 pm Tom Rondeau

filter: adding single_pole_iir_filter blocks.

QA, docs, and GRC.
05c117f3 06/15/2012 07:59 pm Tom Rondeau

filter: updating adaptive FIR filters.

No need for our own adaptive_fir class; can do everything with fir_filter.

With QA code.
5585c712 06/15/2012 12:43 pm Tom Rondeau

filter: adding ssc and fsf versions of filter with associated new Volk kernels.

These routines work and pass QA. They could use some performance work. the FSF is just slightly slower than before; the SCC version is more noticably slower.

Both could benefit, probably, by using SSE2 intrinsics to handle the shorts.
14532d8d 06/11/2012 02:35 am Tom Rondeau

filter: adding ccf version for adaptive filter.
511f3514 05/10/2012 12:17 am Tom Rondeau

filter: wip: working on adaptive FIR filter. Moved ccc and created parent class that is not a gr_block.
274bc141 05/09/2012 02:43 am Tom Rondeau

filter: created polyphase_filterbank parent class to handle some initialization and setting taps of PFB blocks.

Converted pfb_channelizer_ccf over to new parent class. Passes QA.
4f08cb7e 05/09/2012 02:07 am Tom Rondeau

filter: copied over pfb_channelizer to gr-filter with QA and GRC.
0f6af7cf 05/07/2012 02:42 am Tom Rondeau

filter: added fir_filter_with_buffer to gr-filter.

Only fff and ccc versions so far. Needs work on Volk to be followed from fir_filter.
fc98a2a9 05/06/2012 11:36 pm Tom Rondeau

filter: added filter_delay_fc to gr-filter with QA and GRC files.
137cd171 05/06/2012 08:24 pm Tom Rondeau

filter: moved dc_blocker to gr-filter with QA and GRC blocks.
897a6022 05/05/2012 09:52 pm Tom Rondeau

filter: added hilbert xform block with QA and GRC block.
e832b091 05/05/2012 06:41 pm Tom Rondeau

filter: added Parks-McClellen algorithm.

Renamed gr_remez to pm_remez here. Added QA code and fixed coding style.
906fe742 05/05/2012 05:34 pm Tom Rondeau

filter: added firdes for generating FIR filters to gr-filter.

Addes QA code in both Python and C++.
26531c2d 05/02/2012 10:59 pm Tom Rondeau

filter: fixed FIR filter taps and added complex FFT filter.
32f807a8 05/02/2012 08:14 pm Tom Rondeau

filter: Reworking filter to have a set of basic implementation classes for filters of different kinds.

The GR blocks are templated now and call from fir_filters for the volk-specific implemenation.

Note the modification to build_utils.py to accomodate these changes.
f64b971f 05/02/2012 02:10 am Tom Rondeau

filter: work on creating gr-filter top-level component.

Builds but does not bring in libgnuradio-fft.so symbols.
