Abstract:
1. A radio receiver formed as a monolithic integrated circuit comprising: a receiver having an input coupled to an antenna input of said integrated circuit; a demodulator for receiving a modulated signal and outputting a digital data signal, said demodulator including a baseband filter; said receiver and said demodulator being formed on a single monolithic integrated circuit chip; a digital decoder formed on said chip, said decoder for receiving said digital data signal, said digital decoder performing logic functions on said digital data signal and outputting binary data at a data output terminal of said integrated circuit, and control logic having at least one control input; at least one control pin connected to said at least one control input, said at least one control pin for receiving logical high or low control signals generated external to said monolithic integrated circuit; and said baseband filter connected to said control logic, said control signals applied to said at least one control pin causing said control logic to select one of a plurality of discrete frequency response bandwidths of said baseband filter to tailor said frequency response to a particular type of signal received by said receiver.
