Frequency Response Function (Real-Im) VI

Computes the frequency response and the coherence based on the input signals. Results are returned as real part, imaginary part, and coherence.

Typically, time signal X is the stimulus, and time signal Y is the response of the system. Each time waveform corresponds to a single FFT block. You have to pass each time waveform individually to this VI.
