dBm50ohmAny(
n_voltage

)
=> n_dBm

Description

Calculates output power in decibel-milliwatts (dBm) from the specified voltage value for a 50 ohm resistance.

dBm is a unit of level that expresses power level in dB with reference to 1mW. dBm is a dimensionless unit, but because it compares to a fixed reference value, the dBm is an absolute rating.

The power in dBm is calculated using the following formula:

Where, V= Voltage in volt, R= 50 ohm and, 1mW= 0.001 watt

Arguments

n_voltage	Voltage value in volt.
n_constant	Constant value.

Value Returned

n_dBm

Power output in dBm.

Examples

The following example calculates the power in dBm for the voltage value 10 volt and resistance value 50 ohm.

dBm50ohmAny(10 4.342945)

=> 33.0103
