| 20090086107 | RECIEVER SYSTEM FOR MULTIPLE BANDWIDTH TELEVISION CHANNELS - Disclosed is a receiver system, capable of receiving RF signals on television channels of multiple bandwidths. The receiver system includes a tuner, an analog IF filter, an ADC, a mixer module, one or more digital filters, an AGC module and a controller. The tuner converts an RF signal into an IF signal using a mixer frequency. The analog IF filter filters out a fixed band signal from the IF signal.

The output of the digital filters is converted to a base band signal and the power level of the base band signal is controlled by the AGC module. The controller selects a mixer frequency from a group of mixer frequencies based on a function of power of the output of the AGC module by applying each mixer frequency to the tuner. | 04-02-2009 |
| 20090091663 | RECEIVER FOR DIFFERENT TYPES OF RECEPTION SIGNALS - A receiver can handle different types of reception signals, such as, for example, TV and FM-radio signals. In the receiver, a mixer (MIX) mixes a reception signal with an oscillator signal (OOS) so as to obtain a mixer output signal (MOS), which comprises a frequency-shifted version of the reception signal. An intermediate frequency amplifier (IFAMP) applies an amplified mixer output signal (MOSA) to two different intermediate frequency filters: one for first type reception signals and another for second type reception signals. A switchable coupling section (DBTP, SWA) is coupled between the mixer (MIX) and the intermediate frequency amplifier (IFAMP). The switchable coupling section (DBTP, SWA) is switchable to a first state and a second state. In the first state, the mixer output signal (MOS) substantially reaches an input (IAD) of the intermediate frequency amplifier (IFAMP) via a first coupling path (DTBP). In the second state, the mixer output signal (MOS) substantially reaches the input (IAD) of the intermediate frequency amplifier (IFAMP) via a second coupling path (SWA). | 04-09-2009 |
