ifft

rfnetwork.utils.ifft

rfnetwork.utils.ifft(Xw)

Computes the inverse fft on complex-valued data over a positive frequency range. Data should extend down to near DC for accurate results.

Parameters:

Xwnp.ndarray

frequency domain data defined over the positive frequency range. Data should extend down in frequency to the step size of frequency. For example, if the frequency step is 10MHz, the lowest data point should be at 10MHz.

Returns

timenp.ndarray

time vector in seconds

xtnp.ndarray

time domain data, with time as the first dimension followed by the remaining dimensions of Xw
