Method for optimizing the level of RF signals by comparing quality of the RF signals under different operation modes

摘要

A signal processing method includes the steps of tuning to a channel frequency and then measuring quality of the information borne by an information bearing RF signal on the selected channel frequency under a first operation mode, enabling an attenuator and/or an amplifier and then measuring quality of the information borne by the RF signal under a second operation mode, and determining the optimum receiving condition by comparing the quality of the information borne by the RF signal under the first and second operation modes.
