Feed line loss is specified in dB per some length (100 feet or 100 meters is common) at a particular frequency. Antenna gain is given in dB, usually compared to an isotropic or dipole …

Here, the square brackets mean “units of dB”. Notice that this formula is easy to remember because it has lots of tens, hence the “deci-” in “decibels”.

dB measurements may be made using a frequency weighting filter, sometimes called a weighting network, to make the measurement depend on the frequency distribution of the signal's …

Q: OK, so what does dBm mean? A: This notation simply means that we have normalized some power P to one Milliwatt (i.e., P 1 mW )—as opposed to one Watt. Therefore: ( dBm ) = + 50 …

If your claim is rejected, you will receive either a Notice of Denial of Claim for Disability Benefits (Form DB-DEN) or a Notice of Total or Partial Rejection of Claim for Disability Benefits (Form …

Power and Voltage Ratios Expressed in Decibels (dB’s) Bel = log(Power2 / Power1) decibel = 1 dB = 0.1 Bel, hence 10 dB = 1 Bel To express a Power Ratio in dB’s, use dB = 10 log(Power2 …
