From the trial. I found that the system's sensitivity (sensitivity) to indicate the ability to receive signals of radio communication, which is when we enter the RF signal (from a gennerater signal) will cause the interference is reduced to 20 db reduction can be considered as a reference point (20 db Noise. Sensitivity) so the radio receiver with a 20 db, there is little value to NQ sensitivity rather than a dash radio with 20 db with NQ----
