Abstract:
A method for controlling transmitter power in a system including a control element controlled by a control signal, sampling means for taking samples of a signal from the control element, and a detector in connection with the sampling means, an adder and a loop filter, the adder and loop filter forming a controller for receiving a signal which is transmitted by the detector and forms part of a feedback signal for controlling the control element, the method comprising:using a parallel loop between the input and output of the controller, said loop, when becoming activated, keeping a feedback loop closed when a value of the sampled signal is outside a dynamic range of the detector, thereby controlling the transmitter power without discontinuities;wherein when the sampled signal value falls below the dynamic range of the detector, a control signal value that causes a detector input signal of the magnitude of the threshold voltage of the detector, is loaded into a memory.
