35results about How to "Increase implementation flexibility" patented technology

Embodiments of this application provide a signal processing circuit and a related apparatus. Both an input signal and an output signal of the signal processing circuit are analog signals. The signal processing circuit folds the input signal before outputting, thereby reducing a high peak-to-average power ratio of a modulation signal. Because the signal processing circuit directly implements signal folding in an analog domain, a requirement for an analog-to-digital converter can be greatly lowered, and an amplifier is enabled to work in an efficient region.
