摘要:Receiver comprising analog signal processing means (1-9) and intermodulationinterference detection means (10-15) for detecting intermodulation interference
occurring in said analog signal processing means (1-9). According to the invention the gainof said analog signal processing means (1-9) is modulated with a gain modulation signal.The amplitude variation of the output signal of the analog signal processing means (1-9)due to said gain modulation signal is detected and supplied to a first input of a correlator(12). The gain modulation signal is also supplied to a second input of the correlator (12).The correlator (12) causes an intermodulation interference indicative signal to occur at adetection of differences in relative amplitude variations of the output signal of leveldetecting means (13,14) at the first terminal of the intermodulation interferencedetection means (10-15) on the one hand and the gain modulation signal at the secondterminal of the intermodulation interference detection (10-15) means on the other hand.
