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...
Enter either Power Gain (P1/P2) or Voltage gain to calculate the Decibel (dB). Power Gain (P1/P2): OR Voltage Gain (V1/V2): Output Decibels: dB You can also use this calculator to find out the Power Gain and Voltage Gain from the Decibel value. Just enter the Decibel value and...
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...

Conversion of Factor or Ratio to Level Value (Decibels dB) The human perception of loudness (Factor, Ratio, Gain) Converting Decibel to Percentage (%) and Distortion to Decibel Power is like all energy sizes primarily a calculated value. ...
20× log10(1/√2) = (−)3.0103 dB less than the maximum voltage gain. The expressed power gain in dB (power amplification) at the cutoff frequencyfcis 10× log10(½) = (−)3.0103 dB less than the maximum power gain. To use the calculator, simply enter a value. ...
Calculator Use the following tool to calculate the difference between two dBm values. dBm1 dBm2 dB = dBm1-dBm2 Formula PdB= PdBm1– PdBm2 Calculation Example If PdBm1= 30 dBm PdBm2= 10 dBm then, PdBm1– PdBm2= 20 dB Note that this is not the difference in power level between the...
dBm is a power ratio relative to 1mW, dBu and dBV are voltage ratios, relative to 0.775V and 1V, respectively. To use this calculator enter your application data in the section provided, then enter the quantity you wish to convert in the appropriate form element. Tabbing to another field,...
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）...
dB dBV Calculator Launch me!This calculator converts between voltage gain and decibels (dB) and between voltage amplitude and decibel volts (dBV). New! A deep dive into the electronic design of the ultimate high-gain rig-of-death! From system design concepts to individual stage operation, ...
