ABSTRACT:
A cell phone is provided that may be used with multiple radio formats, such as GSM and CDMA. The cell phone includes a receiver that receives radio signals and converts them into electrical signals. An analog to digital converter is connected to the receiver and converts an analog input to a digital output having an adjustable number of bits at an adjustable sampling frequency. A cell phone application specific integrated circuit is connected to the analog to digital converter, which is used to process the digital output to extract encoded telecommunications data in one of the supported radio formats.
