This program shows signals in time domain and
You can choose block, triangle, sawtooth and rectified
The tar.gz file (20 kB) contains the source, my comp program and
the compiled binary.
This electronics program calculates the Bode plot
(amplitude and phase) of simple ladder networks.It is usefull
in HF-electronics for calculating the
frequency response of filters and matching networks.
You can enter the diagram with a few mouseclicks and the
program will do the mathematics involved.
The tgz file (31 kB) contains the complete source, my comp
program and the compiled binary.
This program shows the sidebands of an FM modulated signal as a function of
frequency deviation and modulation frequency.
The tar.gz file (15 kB) contains the source, my comp program and the compiled binary.
A Digital Signal Processing simulator.
When you program a DSP processor, in most cases you start programming filters for audio frequencies.
This program will be tested in a DSP-board with an audio signal from a signal generator.
The output will be made visible on the screen of an oscilloscope.
Most students who have to practise, don't have this equipment at home.
For that reason I have written this program.
This program simulates FIR and IIR filters.
You can enter coefficients for the filters and set samplerate and resolution.
You can examine what happens when the output signal is to large, and how the different filtertypes react on pulses, etc.
The calculation of coefficients can be tedious, so I have made some examples to use a spreadsheet program to calculate
the FIR files.
The tar.gz file (76 kB) contains the source, the compiled binary, a manual and several examples.
