2009-10-12This splits the rate into a fractional an integer value, which allows the ↵Tom Rondeau
loop to adjust the fractional rate while the integer rate keeps the increments moving properly. Allows the max rate deviation to be independent of the integer rate. Scaling of the differential taps also allows alpha and beta to operate independent of the rate when fractional samples per symbol are used. Slightly more tolerant to large signal values, but they still should be close to +/-1.

2009-10-12Working DBPSK implementation with new PFB clock recovery block. The ↵Tom Rondeau
feedforward AGC wasn't playing nicely, the frequency aquistion range was increased to swing half the sample rate in either direction, and the number of filter phases to use was increased to 32.

we dont use test() -> remove it Made the window for the pass band filters integers (take firdes.WIN_XXX). Evaluation fix in param.to_code(). Removed the flagging api and usage from the base classes. added ref scale param to fft and waterfall Switched the python classes to inherit from the base and gui classes. port and param types from an overloaded method todo Replaced TYPES in Port and Param with types parameter. made is_virtual_xxx a block level function, used by port and param classes added stream id type and checking in evaluate avoid loops Recursive resolution of virtual sources. added virtual source and added stream ids, logic to clone in port added rewrite methods to element to separate from validation logic Added virtual sink and logic to clone port. removed repurposing of pads Work on command line options for generated code. renamed the colors dialog to types use pkgpythondir ...

* Fixing a line in the clock recovery algorithm. This works with a bit larger error than there proably should be. * Adding clock sync algorithm using PFB. This works, but needs a bit more work.

2009-08-31Modified log power fft block so ref scale is peak to peak.Josh Blum
Tweaked fft sink autoscale routine to come up with better numbers. Modified scope sink ac couple block to use constant tap. The previous tap calculation would cause failure for very small sample rates.

Added files to Makefile.am for distribution. Added colorbar to spectrogram for magnitude measurement. Fixed spectrogram plotting axis. Adding a spectrogram plot. The axis need work. GR plotter tool handles end of file and files shorter than the block length. Manages window/filter types better. Disables filter types if the designing algorithm doesn't support it (no RRC or Gaussian for equiripple filters). User messages if PyQt and PyQwt are not installed (or found). Setting validators for all edit boxes. Fixing tab order. Adding display for the number of taps in the filter. Adding equiripple band reject filter to filter design app. Adding P-M version of band reject filter. Fixed documentation for optfir band pass filters. Added routine for optfir equiripple filter design code to create complex bandpass filters. Also adds this ability to the filter designer. Added design for Guassian filters. Added design for RRC filters. Added Band Notch filter Adding complex bandpass filter design (for windowed filters only). Adding plotting of group delay. Adding labels to the plots. ...

2009-08-15Added reset method to gr_head and gr_vector_sink. This allows graphseb
containing these blocks to be run more than once with user control over when the reset of the counter and sink occurs. git-svn-id: http://gnuradio.org/svn/gnuradio/trunk@11599 221aa14e-8319-0410-a670-987f0aec2ac5
