Power ratios are common in electronics engineering, especially when handling amplifiers and other active devices. An amplifier's gain is the ratio of the power at its output to the power at its input. Naturally in an amplifier, the output power is higher than the input power so the ratio is...
without regard to the impedance. So a "power amplifier" which needs an input of 1.5 V from a 1000 ohms source to give an output of 30 V into 8 ohms is spoken of as having a gain of 20 × log (30/1.5) = 20 × log (20) = 20 × 1.3 = 26 dB. So "dB" is simply another...
Voltage gain/loss dB Output voltage Volt Find output power by entering input power and power gain/loss (dB): Notice: Power gain is not used in audio engineering. Input power watts Power gain/loss dB Output power Watt Not used in Audio To use the calculator, simply enter a value. The...
In RF active devices this ratio is termed as “gain” which is always >1. If this ratio is <1 it depicts loss which is also also useful in RF systems to "attenuate" power. When operating or analyzing devices like amplifiers or complex active systems like a complete Tx-Rx chain the inp...
(15.4), which relates the received optical power PRX to the transmitted optical power PTX, the gains of the transmit optics GTX and the gain of the receive optics GRX, and the losses that occur on the optical channel, which are the pointing loss LP, the free-space loss LS due to light...

I was just in there adding the cells for room gain and gain from speaker placement. I'm not sure if the spreadsheet can be downloaded. One way to do so is to copy the spreadsheet and paste it into a locally open spreadsheet program. The equations may not copy directly, thou...
