To provide a method and a circuit arrangement (100) for detecting synchronization patterns in a receiver, particularly in a UHF receiver or a VHF receiver, by which the average current consumption in a system with a receiver, particularly a UHF receiver or a VHF receiver, and with a subsequently arranged controller unit (200) can be clearly reduced, - at least a shift register (30) whose input can be impressed with an incoming signal and which is provided for picking up or taking over the signal state pattern particularly determined by the slopes; - at least a slope detector (40) whose input can also be impressed with the incoming signal; - at least a clock recovery unit (50) to be synchronized with the signal and preceded by the slope detector (40), the output of said clock recovery unit being connected to the clock input (30c) of the shift register (30); and - at least a decision unit (60) preceded by the shift register (30) for comparing, particularly continuously comparing the signal state pattern picked up by the shift register (30) and possibly also completely inverted with a predetermined state pattern stored in at least a pattern memory (70) assigned to the decision unit (60) are provided. |
