Abstract
Radio frequency receivers are implemented in a variety of embodiments. In one such embodiment, a radio frequency receiver is implemented 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 can be reduced. Using a slope detector and by taking the signal state in a shift register, the radio frequency receiver may be implemented by synchronizing a clock recovery unit with an incoming signal. The shift register pattern can be compared against a predetermined pattern, and when the patterns correspond to the pattern of each other or to the completely inverted pattern of the other, the signal is enabled for further processing in a controller unit.
