129dba869f Adds Remez filter designer for low, high and band-pass filters. Support
for Hilbert and Differentiator FIR filter designers may be added in the
future.

Adds developer filter viewer tool written in JavaFX to visualize the
frequency and impulse response of FIR filters.  This application is not
intended to be a user application and is specifically for the developer
to analyze filters and filter specifications that will be used in the
code.

NOTE: Java 8 JDK is now required to build this project for version 0.3.x
and forward.  The JavaFX visualizer application and future user
interfaces will use the Java 8 version of JavaFX

fccde3d112 Build 0.1.3 - adds support for 48 kHz audio output from JMBE library for P25 audio. Resolves issue with Automatic Frequency Control on P25 C4FM channels where the channel was not tracking changes in tuner frequency. 2015-05-11 09:37:50 +00:00

bc5080aa4a P25 - updated automatic and direct frequency control to cleanup the code and allow P25 to better track frequency and PPM changes in the tuner and provide a cleaner implementation of the AFC component in the processing chain of all of the other decoders.
Changed C4FM symbol filter to reset frequency tracking values when the tuner's frequency or PPM values change.

Moved all frequency control pieces into the source.tuner.frequency package.

4e0fd9b7b0 Channel Spectral Display
- Adds Channel Spectrum tab to display FFT of the audio output of the currently selected channel
 - Upgrades to JTransforms 3.0 FFT library
 - Adds three new context menus to main and channel spectral displays:
   -- Baseline - affects the vertical rendering baseline of the FFT
   -- Amplification - affects the vertical height of each FFT bin
   -- Averaging - affects how many FFTs are averaged to produce the display
