How to convert gain to dB? – example Let's say we have an amplifier that receives 2 W at the input and delivers 400 W at the output. We can use this dB gain calculator to easily find the power gain in dB: Enter the value of 2 W into the field "Initial power". Choose the val...
Using power we get: Level in dB:L=10× log (power ratio) 3 dB = twice the power 6 dB = four times the power 10 dB = ten times the power 20 dB = hundred times the power To use the calculator, simply enter a value. The calculator works in both directions of the↔sign. ...
Note that the brackets are important and antilog may be shown on calculator keypads as 10xor 10^ and is also usually Shift +log. Use the same formula for dBs to Current gain ratio, and to convert dBs to a power ratio, simply replace the 20 in the formula with 10. An advantage of u...

增益Gain分贝dB 增益Gain分贝dB 分贝(decibel)是量度两个相同单位之数量⽐例的单位,主要⽤于度量声⾳强度,常⽤dB表⽰。“分”(deci-)指⼗分之⼀,个位是“贝”或“贝尔”(bel),但⼀般只采⽤分贝。分贝(dB)是⼗分之⼀贝尔(B): 1B = 10dB。功率量 考虑功率或者强度(intensity)...
What is a pyramidal horn antenna gain calculator? This online pyramidal horn antenna gain calculator is used to calculate the gain (in dB) of the pyramidal horn antenna by entering the aperture area, wavelength, and aperture efficiency. What is a pyramidal horn antenna? Pyramidal horn antenna ...
To use the calculator, simply enter a value. The calculator works in both directions of the ↔ sign.Gain factor v = V2 ⁄ V1 (ratio) for field sizes, e.g. voltage ↔ Amplification level L voltage level dB 0 dB = voltage gain v = 1...
Offsetting is a policy instrument intended to provide flexibility for development. We developed a simple calculator to predict when no net loss is feasible using biodiversity offsetting. Assuming offset ratios ≤10:1 are indicative of operational feasibility and employing a discount rate of 3%, we ...

Antenna gain is the measure of antenna power in decibel (dB), which is equal to10*log(Pout/Pin). Don’t worry about it, just remember that the higher the gain, the more directional an antenna is – more range, narrower beam width. ...
