Transducer impedance decreased when Amplifier is connected

I am trying to measure beam pattern and impedance curve of a transducer from 70 to 120 khz. To get a nice plot, i have to use an amplifier(op-amp +-14Vs and Gain=14db) between a Signal Generator(Whose ...

Can we think of an impedance or an admittance as a case for a transfer function?

We define impedance as the complex ratio of potential (voltage) over flow (current). We can describe it as how much a system "impedes" the flow according to a potential applied to it. But wouldn't it ...
