Abstract
A very low intermediate frequency receiver and methods for controlling the same. One method includes providing, using a local oscillator, a first intermediate frequency, detecting, using an interferer detector, an adjacent or alternate channel interference signal and an image of the adjacent or adjacent channel interference signal causing interference with a desired signal, and determining, using an electronic processor, whether the desired signal is an analog signal. In response to determining that the desired signal is an analog signal, the method includes controlling, using the electronic processor, the local oscillator to provide a second intermediate frequency. In response to determining that the desired signal is not an analog signal, the method includes determining, using the electronic processor, a switching condition based on the desired signal, and controlling, using the electronic processor, the local oscillator to provide the second intermediate frequency in response to determining the switching condition.
