The circuit was successfully tested using a 1-kHz sine wave for the input with an amplitude of 4.5 V, and it produced a 1-V amplitude sine-wave output using a 1-V reference for the set point.

Measuring the amplitude, phase, and impedance responses of electronic, electro-acoustic, and other systems, the 10-Hz to 4-MHz C60 impedance and frequency response analyzer displays results using a ...
