datacomm-lab's Issues

Thresholding function

The Signal class should contain a function like sample(), but returns the sampled result sampled at the original signal's sampling rate and containing only binary values.

E.g.

const sig = new Signal(2048);
sig.signal = [1, 2, 3, ...];

const samp = new Signal(8);
samp.signal = sig.sample(8);

const thresh = samp.sample(2048).map((x, i) => (x > 0 ? 1 : 0));

Repeated filtering

Request for a new function for filtering multiple times.

E.g.

const filt = new Filter(FilterType.LPF, 100, 2048, 16);
const filtered = filt.sample_all([1, 2, 3, ...]);

Square wave gives null values

Generating a square wave:

const wave = new WaveSignal(WaveSignalType.SQUARE, 8, 2);
console.log(wave.signal)

gives:

[1, 1, null, null, 1, 1, null, null]

instead of:

[1, 1, 0, 0, 1, 1, 0, 0]
