TFGrid.dt

property TFGrid.dt

The time grid step size of the analytic representation, with units of s.

The time step is used as the differential of Fourier transforms. Multiplying the input of the transform by this factor will preserve the integrated absolute squared magnitude of the transformed result:

a_v = fft.fft(a_t, fsc=dt)
np.sum(np.abs(a_t)**2 * dt) == np.sum(np.abs(a_v)**2 * dv)

Returns:
