Measuring mechanical impedance (force/velocity) with channel A: acceleration sensor and channel B: force (impulse hammer) as inputs. The transfer function can be obtained, but the coherence function cannot.
Please calculate the average.
Measurement of coherence functions always requires averaging of the spectrum.
It cannot be measured well on a time axis average.
