Hallo Allemaal,
Wederom een leuk stukje Engels leesvoer van mij. Dit keer onder de pakkende titel: "dB or not dB? Everything you ever wanted to know about decibels but were afraid to ask…".
Het is 35 pagina's leesplezier waarin onder andere vragen zoals de volgende worden beantwoord:...
"True or false: 30 dBm + 30 dBm = 60 dBm? Why does 1% work out to be -40 dB one time but then 0.1 dB or 0.05 dB the next time? These questions sometimes leave even experienced engineers scratching their heads. Decibels are found everywhere, including power levels, voltages, reflection coefficients, noise figures, field strengths and more. What is a decibel and how should we use it in our calculations? This Application Note is intended as a refresher on the subject of decibels."
Groetjes, Johan.
Everything you ever wanted to know about decibels.
