Enter the load impedance (ohms) and the characteristic impedance (ohms) into the Calculator. The calculator will evaluate the Reflection Coefficient. 

Reflection Coefficient Formula

RC = (Zl-Zo)/(Zl+Zo)

Variables:

  • RC is the Reflection Coefficient ()
  • Zl is the load impedance (ohms)
  • Zo is the characteristic impedance (ohms)

To calculate Reflection Coefficient, divide the difference between then load and characteristic impedance by the sum of those impedance.

How to Calculate Reflection Coefficient?

The following steps outline how to calculate the Reflection Coefficient.

  1. First, determine the load impedance (ohms). 
  2. Next, determine the characteristic impedance (ohms). 
  3. Next, gather the formula from above = RC = (Zl-Zo)/(Zl+Zo).
  4. Finally, calculate the Reflection Coefficient.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

load impedance (ohms) = 76

characteristic impedance (ohms) = 34
