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 ...

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 ...

Termination resistors and the ratio units of voltage and power — dB — are interrelated topics. The dB units can refer to voltage or power, and conversions between voltage dB units and power dB units ...

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 ...

A decibel is most accurately described as a logarithmic method for measuring the magnitude of a signal relative to a given reference level. Only when we know what the reference point is does the ...

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.
