wavegen

wavegen is a wavefrom generator made with 🦀

How to use it?

1. Add wavegen to your project:

[dependencies]
wavegen = "0.3"

Or, to use the no_std version (custom global allocator is required):

[dependencies]
wavegen = { version = "0.3", default-features = false, features = ["libm"] }

2. Define a waveform with sampling frequency and function components:

let waveform = wf!(f64, 200, sine!(frequency: 100, amplitude: 10), dc_bias!(20));

3. 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.

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.

MSRV

The Minimum Supported Rust Version is 1.56.1.
