This is an user friendly function generator in C. You can simple way generate different waveforms and do operations with them.
SIMULATION
- You can set the simulation time
- You can add the number of simulaton steps
WAVEFORMS
- periodic signals: sine, square, triangle
- non-periodic signals: square root, Log, Log2, Log10, Lin
OPERATIONS
- math: add, sub, mul, div
OUTPUTS
- showWaves: makes a list with two columns in console
- writeCSV: makes a CSV file with content of "showWaves"
- writeHeader: makes a standard C header file with two arrays
To use this repository, you will need:
- GCC (or similar C compiler)
git clone https://github.com/vargalaszlo87/fGen.git
If you use Windows
🔴 Important! Check the gcc --help command in your Command Prompt. If it doesn't work you need add GCC to system variable (PATH).

Insert your headers:
#include "fgen.h"Create a simulation:
struct generator g;
g.step = 10000; /* number of steps */
g.simulationTime = 0.1755; /* time in seconds */Create a waveform:
struct waveform signal;
signal.amplitude = 230; /* set amplitude */
signal.frequency = 120; /* set frequency */
makeSine(&g, &signal);Generate an output:
showWaves(&signal);src/main.c file:
#include <stdio.h>
#include <stdlib.h>
#include "fgen.h"
int main(int argc, char *argv[]) {
// create a simulation
struct generator g;
g.step = 10000;
g.simulationTime = 0.1755;
// create a sine signal
struct waveform signal;
signal.amplitude = 230;
signal.frequency = 120;
makeSine(&g, &signal);
// crate a sine noise-signal
struct waveform noise;
noise.amplitude = 23;
noise.frequency = 5000;
makeSine(&g, &noise);
// create a ramp (sqrt function)
struct waveform ramp;
makeSqrt(&g, &ramp);
// make an 'out' waveform
struct waveform out;
// add two signals (out = signal + noise)
// multiply two signals (out = out * ramp)
out = addWaves(&g, &signal, &noise);
out = mulWaves(&g, &out, &ramp);
// write to stdout and CSV
showWaves(&out);
writeCSV(&out);
return 0 ;
