jdsp

jdsp is my initial attempt at building a library for signal processing in the Java language.

Install

To install, perform the following actions.

1. Build

   $ gradle build

2. Add the jar file to the $CLASSPATH
3. Generate Javadoc

   $ gradle javadoc

Examples

Example: Creating and applying a Filter object

import jdsp.filters.Filter;
// constructor defaults to moving average filter
Filter f = new Filter(11);
// update filter
f.designFilter(101, "HAMMING", 0.1);

// apply filter
float[] data0 = {1.0f, 2.0f, 3.4f};
float[] data1 = {1.0f, 2.0f, 3.4f};
float [] out1, out2;
out1 = f.applyFilter(data0);

// continue filter on second data segment
out2 = f.applyFilter(data1);

Example Plots and Figures

Some functionality was created with Java Swing to provide visual tools to be used with this package.
