Radio Voltage Reflection Return Loss: solve voltage reflection-coefficient magnitude: Rearrange the radio voltage reflection return loss relationship and solve for voltage reflection-coefficient magnitude.

Age 5Explain it to a 5-year-oldStart with a picture

Imagine using Radio Voltage Reflection Return Loss: solve voltage reflection-coefficient magnitude to answer this question: rearrange the radio voltage reflection return loss relationship and solve for voltage reflection-coefficient magnitude? Enter return loss in decibels and voltage-ratio decibel conversion coefficient; the calculator shows voltage reflection-coefficient magnitude. For example: voltage-ratio decibel conversion coefficient=8.685889638 and voltage reflection-coefficient magnitude=0.1 produce return loss in decibels=19.999999999850246. The answer tells you voltage reflection-coefficient magnitude.

Age 15Explain it to a 15-year-oldConnect it to the formula

Return loss is minus twenty times log base ten of voltage reflection magnitude; the coefficient 20 divided by natural-log ten enables the equivalent natural-log form. This page isolates voltage reflection-coefficient magnitude and verifies it in the original relationship. The rule is b=e^(−c/a). Its input values are return loss in decibels, voltage-ratio decibel conversion coefficient, and the main result is voltage reflection-coefficient magnitude. For example: voltage-ratio decibel conversion coefficient=8.685889638 and voltage reflection-coefficient magnitude=0.1 produce return loss in decibels=19.999999999850246.

CollegeExplain it at college levelState the model precisely

This calculator evaluates the stated radio voltage reflection return loss: solve voltage reflection-coefficient magnitude relation over the valid real-number domain stated below. The implemented relation is b=e^(−c/a), evaluated from return loss in decibels, voltage-ratio decibel conversion coefficient to produce voltage reflection-coefficient magnitude. Return loss is minus twenty times log base ten of voltage reflection magnitude; the coefficient 20 divided by natural-log ten enables the equivalent natural-log form. This page isolates voltage reflection-coefficient magnitude and verifies it in the original relationship. Reflection magnitude must be positive and no greater than one for a passive load; return loss is not insertion loss.

Inputs and valid domain

  • return loss in decibels must be a finite real number.
