QuestionQ65

Performance Optimization

When measuring signal strength, dBm is commonly used, and 0 dBm represents 1 mW of power.

What does -20 dBm represent?

  • A .01 mW
  • B 1 mW
  • C .1 mV
  • D 10 mW
Explanation

A decrease of 20 dB from the 0 dBm reference reduces power by a factor of 100. Therefore, -20 dBm equals 0.01 mW.
