A radio front end utilizes at least one band pass filter to pass only the appropriate frequency band. Once the desired frequency band has been isolated it is converted to a digital format in an analog to digital converter and a digital signal processing device interprets the signal.

A DC/DC converter features a programmable controller in a feedback control loop thereof. The programmable controller enables easy changes to operating parameters by reprogramming the controller's application software. Additionally, the converter features a hardware-implemented fault protection circuit which shuts down the converter's switching transistor upon controller failure.

A method and radio receiver provide matching of output levels for a plurality of receiver input sources. The method includes the step of creating alignment information for the plurality of input sources. The method further provides for storing the alignment information in a computer readable memory, and converting a required output level into a matched output level. The matched output level is based on the alignment information contained in the computer readable memory corresponding to the selected input source, and the required output level is obtained from a volume control setting. Thus, creation, storage, and retrieval of alignment information allows for real-time matching of output levels for multiple input sources.
