aspcore.fouriertransform.ifft

aspcore.fouriertransform.ifft(freq_signal)

Computes the inverse FFT

Computes along the first axis, and moves the resulting time axis to the last axis. Uses the opposite time convention as numpy.fft.

Parameters:

freq_signal (ndarray of shape (num_freqs, ...)) – The signal to be transformed. The first axis should correspond to frequency

Returns:

time_signal – The transformed signal

Return type:

ndarray of shape (…, num_samples)
