Patent ID: 7756500

Claim:
A tuner for receiving information signals within a channel selected from within a plurality of channels within a predetermined frequency band, the tuner comprising: a first filter for providing a passband, the passband being characterized by a bandwidth sufficiently broad to admit signals in at least one of the plurality of channels with lesser attenuation than other signals; an input port for receiving information signals and conducting the received information signals to the first filter; an output port for conducting any signals having been admitted by the first filter; and superheterodyne circuitry including a mixer and a second filter for processing any signals coupled thereto and to provide them via a second output port and discriminating the received information signals within the selected channel, wherein at least one of the first filter and the second filter comprises active and passive elements including an artificial inductance, and wherein the first filter comprises: a filter selection signal port for receiving a filter selection signal; and, a plurality of bandpass filters each including a decoder responsive to the filter selection signal for designating a corresponding one of the plurality of passbands for asserting a switch ON signal and a switch for activating the bandpass filter in response to the switch ON signal from the decoder and for otherwise maintaining the bandpass filter in an OFF state.
