Wanted signal is 3 dB above the sensitivity point
(BER = 10−3); unmodulated interferer is at the center
of the adjacent channel; rejection measured as the
difference between the interferer level and the
wanted signal level in dB

Wanted signal is 3 dB above the reference sensitivity
point (BER = 10−2); modulated interferer (same
modulation as wanted signal) at the center of the
adjacent channel; rejection measured as the
difference between the interferer level and reference
sensitivity level in dB

Wanted signal (2FSK, 9.6 kbps, ±4 kHz deviation) is
3 dB above the sensitivity point (BER = 10−3), modu-
lated interferer

Wanted signal (2FSK, 9.6 kbps, ±4 kHz deviation) is
10 dB above the sensitivity point (BER = 10−3); modu-
lated interferer (2FSK, 9.6 kbps, ±4 kHz deviation) is
placed at the image frequency of fRF − 200 kHz; the
interferer level is increased until BER = 10−3
