What is the meaning of DB in physics?

The decibel (symbol: dB) is a relative unit of measurement corresponding to one tenth of a bel (B). It is used to express the ratio of one value of a power or field quantity to another, on a logarithmic scale, the logarithmic quantity being called the power level or field level, respectively.

What is the DB level in dB?

The dB level can be viewed as relative gain of one level vs. other level, or absolute logarithmic scale level for well known reference levels. Decibel is a dimensionless unit. The ratio in bels is the base 10 logarithm of the ratio of P 1 and P 0:

What is the difference between Decibel and DB?

Decibel is used to indicate the level of acoustic waves and electronic signals. The logarithmic scale can describe very big or very small numbers with shorter notation. The dB level can be viewed as relative gain of one level vs. other level, or absolute logarithmic scale level for well known reference levels. Decibel is a dimensionless unit.

What is the difference between DB and dBμV?

dB (μV/m) – electric field strength relative to 1 microvolt per meter. The unit is often used to specify the signal strength of a television broadcast at a receiving site (the signal measured at the antenna output is reported in dBμV). dB (fW) – power relative to 1 femtowatt.
