Next Step Substitute values of Variables

∴

I L = 20 \cdot \log 10 (\frac{100V}{50V})

Next Step Prepare to Evaluate

∴

I L = 20 \cdot \log 10 (\frac{100}{50})

Next Step Evaluate

∴

I L = 6.02059991327962dB

LAST Step Rounding Answer

∴

I L = 6.0206dB

Functions

Insertion Loss

Insertion loss is the loss of signal power resulting from the insertion of a device in a transmission line or optical fiber and is usually expressed in decibels (dB).

Symbol: I_L

Measurement: NoiseUnit: dB

Note: Value should be greater than 0.

Formulas to find Insertion Loss

Voltage

Voltage is the pressure from an electrical circuit's power source that pushes charged electrons (current) through a conducting loop, enabling them to do work such as illuminating a light.

Symbol: V_t

Measurement: Electric PotentialUnit: V

Note: Value should be greater than 0.

Formulas to find Voltage

Input Signal Amplitude

Input Signal Amplitude is the maximum amplitude or peak value of the input signal, which is usually a sinusoidal signal, and is measured in units of volts or decibels relative to a reference level.

Symbol: V_in

Measurement: Electric PotentialUnit: V

Note: Value should be greater than 0.

Formulas to find Input Signal Amplitude

log10

The common logarithm, also known as the base-10 logarithm or the decimal logarithm, is a mathematical function that is the inverse of the exponential function.

Syntax: log10(Number)

FAQs on Insertion Loss

What is the formula to find Insertion Loss?

The formula of Insertion Loss is expressed as Insertion Loss = 20*log10(Voltage/Input Signal Amplitude). Here is an example- 6.0206 = 20*log10(100/50).

How to calculate Insertion Loss?

With Voltage (V_t) & Input Signal Amplitude (V_in) we can find Insertion Loss using the formula - Insertion Loss = 20*log10(Voltage/Input Signal Amplitude). This formula also uses Common Logarithm (log10) function(s).

Can the Insertion Loss be negative?

No, the Insertion Loss, measured in Noise cannot be negative.

Which unit is used to measure Insertion Loss?

Insertion Loss is usually measured using the Decibel[dB] for Noise. Neper[dB], MilliDecibel[dB] are the few other units in which Insertion Loss can be measured.
