    phase-unwrap

    1D phase unwrapping

    Example

    var ndarray = require("ndarray")
    var unwrap = require("phase-unwrap")
    var plot = require("plotter").plot
     
     
    //Create a signal
    var x = ndarray.zeros([100])
    require("ndarray-fill")(x, function(i) {
      return (0.25 * i) % (2.0 * Math.PI)
    })
     
    //Plot input signal
    plot({
      data:  Array.prototype.slice.call(x.data),
      filename: "input.svg"
    })
     
    //Unwrap
    unwrap(x)
     
    //Plot unwrapped signal
    plot({
      data:  Array.prototype.slice.call(x.data),
      filename: "unwrapped.svg"
    })

    And here are the results:

    Input signal

    Unwrapped signal

    Install

    npm install phase-unwrap
    

    require("phase-unwrap")(signal)

    Unwraps the phase angle of a signal whose values are between 0 and 2pi to a continuous signal.

    • signal is a 1D ndarray of values

    Returns An signal. Note that the unwrapping modifies signal.
