Norwood, Mass. – A logarithmic converter chip from Analog Devices Inc. offers optical power-measurement accuracy of up to 0.05 dB over an 80-dB optical dynamic range. The chip can easily be designed ...

Engineers and technicians who work with oscilloscopes are used to seeing waveforms that plot a voltage versus time. Almost all oscilloscopes these days include the Fast Fourier Transform (FFT) to view ...

If you’ve hung around electronics for any length of time, you’ve surely heard of the decibel (often abbreviated dB). The decibel is a measure of a power ratio. Actually, the real measure is a bel, but ...

Editor's Note: We have strived to maintain accessibility in our Bring Science Home activities by limiting the required technology. We recognize technology is now more widely available than it was when ...

Two new RF power detectors from ADI, the ADL5903 and ADL5506, provide wide dynamic range, temperature stability and accurate measurement of signal power from small packages with low-power operation.
