Voltage to dbm converter

This calculator converts between watts, dBm, volts and dBmV. Select the Impedance then enter any one of the other parameters below and the rest will be calculated automatically. Either your browser does not support Javascript, you have disabled it or there is a problem with my page.

Note: Integers numbers without a decimal period or exponent notation are considered accurate up to 15 digits and the maximum number of digits after the decimal point is In this calculator, E notation is used to represent numbers that are too small or too large.

E-notation is commonly used in calculators and by scientists, mathematicians and engineers. We work hard to ensure that the results presented by TranslatorsCafe.

A C-message weighing filter mentioned in the definition of the dBrnC unit is employed for measuring signal-to-noise ratio. It was developed in North America for old-style telephones. The aperture of this manual fish-eye lens is set at 5. The Wi-Fi transmitter of this Linksys router can transmit The sensitivity of this Shure PG48 microphone is — Most professional headphones are capable of producing sound pressure exceeding 85 dB A , which is the maximum permissible sound pressure allowed to affect human hearing during a working day.

Introduction History Definition Classification of Logarithmic Units Logarithmic Units for Amplitude and Power Examples of Relative Logarithmic Quantities and Units Examples of Absolute Logarithmic Units and Quantities in Decibels with Suffixes and Reference Values Introduction The sound power of a Saturn V rocket is ,, W or dB SWL A logarithmic scale is often used when there is a large range of quantities like sound pressure, earthquake strength, light intensity, various frequency-dependent values like musical intervals, in antenna engineering, electronics, acoustics, RF engineering.

History John Napier Neper. Source: Wikipedia Logarithms were invented because they allowed turning multiplication into addition, which can be made much faster than multiplication. Source: Wikipedia A key tool for the practical use of logarithms was the table of logarithms. Definition The logarithm is the inverse operation to exponentiation. Digital sound level meter Relative logarithmic units , on the other hand, are used to express a physical value as a ratio or proportion of another physical value, for example in electronics where a decibel dB is commonly used to express the difference between two signals having arbitrary amplitudes.

Logarithmic Units for Amplitude and Power Power is proportional to amplitude squared. Examples of Relative Logarithmic Quantities and Units Common units dB decibel — a dimensionless logarithmic unit, which is used to express ratios of two arbitrary values of the same physical quantity. British thermal unit per hour. Share dBm dBm , power dBm is an abbreviation for the power ratio in decibel dB of the measured power referenced to one milliwatt mW. Milliwatt -. Kilocalories per hour -.
