WebOct 5, 2024 · The decibel scale is mostly used in electronics to express amplitude or power in preference to percentages or arithmetic ratios. The decibel scale is a useful measure since the overall decibel gain from a series of components (amplifiers and attenuators) can simply be determined by summing all individual components’ gains. Telecommunications WebThe utility of dB comes from two properties: The logarithmic scale applies conveniently to situations where you have a huge dynamic range. For example, in an RF system, you might have signals with powers ranging from picowatts to megawatts. Secondly, the logarithmic scale converts multiplication to addition, which is convenient.

WebApr 5, 2024 · The decibel scale defined in terms of the sound wave intensity is given by the relation. L l = 10log(l / l 0) where I is the intensity of the sound wave and I 0 is the reference value. The form of the equation looks similar to that for SPL that we defined above except that the multiplier in front of the log is 10 instead of 20.
