    Patent number: 7383140
    Abstract: A method for measuring the value of an electronic component, including applying a voltage or a current signal to the electronic component, where the signal has a first tone and a second tone of a different frequency, measuring a response signal from the electronic component, where the response signal also has a first tone and a second tone, applying signal processing on the measured response signal to generate a frequency domain signal, and calculating the value of the electronic component by using a relationship between the first tone of the response signal and the second tone of the response signal.
