heterodyne.m

Signal heterodyne from wall clock time into the rotating frame. Uses a GPU if one is available.

Syntax

    heterodyne(dt,exp_data,car_freq)

Parameters

  dt         - time step in the input data, seconds

  signal     - wall clock time signal, a column vector

  freq       - frequency to be demodulated, Hz

Outputs

  X, Y       - in-phase and out-of-phase parts of the
               rotating frame

Notes

The signal must be sampled with at least four points per period of the frequency being demodulated.
