摘要:
In a circuit for deriving a signal dependent on the direction of change of the reception field intensity in a radio receiver controllable by a microcomputer, outside the microcomputer there is a comparator to which the signal representing the current field intensity and a signal generated by the microcomputer and representing the field intensity at a previous time can be taken. An output signal from the comparator can be taken to the microcomputer.
