PCT No. PCT/DE94/00317 Sec. 371 Date Mar. 6, 1994 Sec. 102(e) Date Mar. 6, 1994 PCT Filed Mar. 22, 1994 PCT Pub. No. WO94/22226 PCT Pub. Date Sep. 29, 1994In a circuit arrangement for deriving a signal dependent on the change direction of the incoming signal level in a radio receiver, controllable by a microcomputer, a comparator is provided outside the microcomputer to which a signal representing the respective signal strength and a signal generated by the microcomputer representing the signal strength at an earlier point in time can be supplied. An output signal from the comparator can be supplied to the microcomputer.
