wavegen

wavegen is a wavefrom generator made with 🦀

How to use it?

1) Add wavegen to your project:

toml [dependencies] wavegen = "0.4" Or, to use the no_std version (custom global allocator is required):

toml [dependencies] wavegen = { version = "0.4", default-features = false, features = ["libm"] }

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

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

3) Turn it into an iterator and sample:

rust 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 1.60.

Breaking changes

0.2

• Braking change in how macros are annotated, changing the annotation form from frequency = n to frequency: n

0.4

• Waveform::get_sample_rate renamed to Waveform::sample_rate and now returns a borrowed values, as per rust API specs.
• Waveform::get_components_len removed. The functionality can be achieved by a new getter Waveform::components.
