Transfer Function PtByPt (Not in Base Package)

Computes the single-sided transfer function, also known as the frequency response, from the time-domain Stimulus Signal and Response Signal from a network under test.

initialize, when TRUE, initializes the internal state of the VI.
stimulus signal x is a time-domain signal, usually the network stimulus.
response signal y is a time-domain signal, usually the network response.
dt is the sample period of the time-domain signal, usually in seconds. dt is also

,

where is the sampled frequency of the time-domain signal.

sample length is the length of each set of incoming data. The VI performs computation on each set of data. The default is 100. sample length must be greater than zero.
Frequency Response Mag is the single-sided frequency response spectrum of the network. This is the amplitude gain of the network.
Frequency Response Phase is the single-sided phase response spectrum of the network. This is the network phase in radians.
df is the line frequency interval of the frequency response spectra, in hertz, when dt is in seconds.
error returns any error or warning condition from the VI. Refer to Point By Point Error Codes for more information about these conditions.
