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.
