Enter the overall noise figure (dB) and the noise floor (dB) into the Calculator. The calculator will evaluate the Receiver Sensitivity. 

Receiver Sensitivity Formula



  • RS is the Receiver Sensitivity (dB)
  • OSF is the overall noise figure (dB)
  • NF is the noise floor (dB)

To calculate Receiver Sensitivity, add the overall noise figure to the noise floor.

How to Calculate Receiver Sensitivity?

The following steps outline how to calculate the Receiver Sensitivity.

  1. First, determine the overall noise figure (dB). 
  2. Next, determine the noise floor (dB). 
  3. Next, gather the formula from above = RS = OSF + NF.
  4. Finally, calculate the Receiver Sensitivity.
  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.

overall noise figure (dB) = 100

noise floor (dB) = 200
