From the experiment, it was found that the sensitivity of the system (sensitivity) to indicate the ability to receive signals of radio communication, when we enter the signal. RF (from signal gennerater) resulted in reduced noise, and reduced 20 dB is considered as the reference point (20 dB Noise.Sensitivity), so the receiver with 20 dB NQ is less, the more sensitive than air and วิทยุที่มี 20 dB NQ very valuable!
