decibel

[SOLVED] Look at my next post to see four function for calculating decibels! hi, I'm working with audio and build a function to find out the Dezibel's of an audio signal: B4X: factor=level/SamplingRate Decibel = Logarithm(factor*factor,10)*10 this works as expected and return the decibels of...

hi, I'm working with audio and build a function to find out the Dezibel's of an audio signal: B4X: factor=level/SamplingRate Decibel = Logarithm(factor*factor,10)*10 this works as expected and return the decibels of an audio signal as in AUDACITY But now I need the reverse case. I have a...

When designing or working with amplifier and filter circuits, some of the numbers used in the calculations can be very large or very small. For example, if we cascade two amplifier stages together with power or voltage gains of say 20 and 36, respectively, then the total gain would be 720...
