wavegen
wavegen
is a wavefrom generator made with 🦀
How to use it?
- Add
wavegen
to your project:
[dependencies]
wavegen = "0.4"
Or, to use the no_std version (custom global allocator is required):
[dependencies]
wavegen = { version = "0.4", default-features = false, features = ["libm"] }
- Define a waveform with sampling frequency and function components:
let waveform = wf!(f64, 200., sine!(frequency: 100., amplitude: 10.), dc_bias!(20.));
- Turn it into an iterator and sample:
let some_samples: Vec<f64> = waveform.iter().take(200).collect();
Refer to documentation for more exhaustive usage examples.
Show me some examples!

Plot charts
- Simple sine
- Two superposed phase-shifted sines
- "Real life" example: 300Hz sine signal with 50Hz interference noise
- Sawtooth
- Superposition of sine + sawtooth
- Square wave
- Superposition of Sine, Square and Sawtooth with different frequencies
All above examples are generated with simple program found in examples/plot.rs
. Run cargo run --example plot
to generate them yourself.
