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.

Abstract: Low dielectric absorption component connection points are created on a printed circuit board by cutting apertures in the board surrounding the points, leaving only narrow stems still connecting the resulting island to the board.

Abstract: The frequency range and accuracy of a commercially available RMS converter is improved by providing an improved rectifier ahead of the converter's internal rectifier. The improved rectifier switches between the input signal and an inverted version of the input signal in response to a high speed comparator. The improved rectifier can also incorporate range selecting circuitry.
