Abstract: An input signal (IN) is filtered (605) to remove aliases and a switched capacitor network (610) undersamples this signal to provide a downconverted, near-baseband signal. An amplifier (615) adjusts the amplitude of this signal to match a digitizer (620). The digitized output is converted into first phase and second phase signals which are then filtered (640) and decimated (645) to further reduce the sampling rate. The downconverted first and second phase signals, rather than higher frequency signals, control the gain function (AGC) for the amplifier (615). The switched capacitor network (610) provides for both tuning and downconversion of the desired signal to a lower frequency for further processing, thus reducing the frequency and power requirements of an associated amplifier and analog-to-digital converter (digitizer).

Abstract: A method of operating a radio having a plurality of station preset pushbuttons includes assigning to the preset pushbuttons a first group of radio frequencies associated with a first country. A spectrum of radio frequencies is scanned. A signal quality metric is measured for each of the scanned frequencies. A country of origin is determined for each of the scanned frequencies. A country in which the radio is disposed is ascertained dependent upon the measuring step and the determining step. If the country in which the radio is disposed is different from the first country, then either the preset pushbuttons are automatically re-assigned to a second group of radio frequencies associated with the country in which the radio is disposed, or a user is provided with an option to re-assign the preset pushbuttons to the second group of radio frequencies.
