Abstract
A digital Radio Frequency (RF) receiver may exhibit image frequencies and these image frequencies may be mathematically related to the intermediate frequency (IF) that is utilized for transmission and reception. In accordance with an embodiment, channel switching may be performed to identify an appropriate receive frequency in the presence of image frequencies on other channels. In accordance with another embodiment, data on a receive channel is evaluated to determine whether the data is inverted, and then appropriate correction may be performed on subsequently received data.
