Negative feedback

Nonlinear distortion called harmonic distortion can be measured with an oscilloscope.

The input to a negative-feedback amplifier can only be a voltage.

The conversion factor for the current-controlled voltage source (ICVS)is called transconductance and expressed in siemens (mhos).

The voltage-controlled voltage source voltage gain of the forward and feedback paths is called
