Abstract: An antenna diversity receiver is disclosed. The diversity receiver has a multipath detector for controlling an antenna selective switching circuit. The switching circuit couples one of a plurality of antennas to a RF receiver input. The receiver allows suppression of adjacent channel interferences without unwanted side effects by employing a switching disabling circuit to automatically disabling the switching circuit when the signal delay between the occurrence of multipath distortions in the RF reception signal and the switching between antennas exceeds a predetermined critical signal delay value.

Abstract: Disclosed is a test module (1) for comparative testing of an electronic component (2) and a simulation module (3) that simulates the function of the electronic component (2) essentially in the form of a software program. The test module (1) has an input/output interface to an external module (4) interacting with the electronic component (2) to be tested and also to the electronic component (2) and the simulation module (3). Equivalent input interfaces of the electronic component (2) and of the simulation module (3) are connected to one another by the test module (1). In addition, the test module (1) has a comparator (6) for comparing output signals from the electronic component (2) and from the simulation module (3) and has a memory log (7) linked to the comparator (6). The inventive test module (1) permits a rapid comparative test of the functions of the electronic component (2) and of the simulation module (3).
