dBmPower (watts)Voltage RMSVpof sinusoid Why is the bandwidth and the cutoff frequency found at the level of "−3 dB"? Why we always take 3 dB down gain of a filter? Full width at half maximum (FWHM). Answer: That is the point where the energy (power) is fallen to the value ...
Will you add my character to DBM? ...no. Want to see my drawings? Can you give me advice? We're not teachers. Plus the internet is filled with tutorials and advices. I'm a cartoonist, and would like to participate to DBM Other cartoonists make the special chapters, on a script by...

Decibels: dB, dB(A), dBA, dB(C), dBV, dBm and dBi? What are they all? The decibel (dB) may be a logarithmic unit wont to measure sound level. it's also widely utilized in electronics, signals and communication. The dB may be a logarithmic way of describing a ratio. The ratio ...
These formulas are used to convert back and forth between input- and output-referenced P1dB values: P1dBOutput = P1dBInput + (Gain - 1) dBm P1dBInput = P1dBOutput - (Gain - 1) dBm The following table of values was used to create the chart shown near the top of the page. ...
dBm : dBm indicates dB referenced to 1.0 milliwatt. One milliwatt = zero dBm. Thus P1 in above dB equations becomes 1.0 mW consequently 10 dBm = 10 mW, 30 dBm = 1W… dBV : dBV indicates dB referenced to 1.0 V. One volt = zero dBV. Thus U1 in above dB equations becomes 1.0 V co...
