Abstract
In order to detect a received signal quickly and reliably, an integrated circuit for detecting a received signal has an intermediate frequency detector which supplies a first search run stop signal if the intermediate frequency lies within a given range. Furthermore, a field-strength comparator is provided which supplies a second search run stop signal if the field-strength of the received signal exceeds a field-strength setpoint value. In addition, a multipath comparator is provided which supplies a third search run stop signal if the multipath signal exceeds a specific multipath setpoint value. The three search run stop signals are logically combined with one another by an AND gate and the result is made available as a static output signal and is provided as an input signal for a microprocessor.
