摘要： An IC of a front end circuit which can be ready for various television broadcasting systems is provided. The front end circuit includes tuning circuits 12A to 12C and 14A to 14C and high frequency amplifiers 13A to 13C individually corresponding to a plurality of reception bands of television broadcasts. The front end circuit further includes a switch circuit 11 for selectively supplying reception signals to the tuning circuits 12A to 12C, and a switch circuit 15 for selectively extracting outputs of the tuning circuits 14A to 14C. The front end circuit further includes mixer circuits 21I and 21Q to which an output of the switch circuit 15 is supplied, and a PLL 30 for supplying local oscillation signals SLOI and SLOQ having phases orthogonal to each other to the mixer circuits 21I and 21Q. The front end circuit further includes a complex band-pass filter 24 to which outputs of the mixer circuits 21I and 21Q are supplied, and an output circuit 25 for mathematically operating an output of the complex band-pass filter 24 and outputting an intermediate frequency signal SIF.

摘要： A channel selection section (17) receives a broadcast signal containing analog broadcasting and a broadcast signal containing digital broadcasting and selects one of the broadcast signals. A variable gain amplifier (25) amplifies the selected broadcast signal by a gain in accordance with a gain control signal. A digital broadcast signal demodulation section (33) demodulates a broadcast signal amplified by the variable gain amplifier (25) and provides a value based on a signal level of the broadcast signal, as the gain control signal. An analog broadcast signal demodulation section (28) demodulates analog broadcast signals which are contained in the broadcast signal selected by the channel selection section and which have passed through the filters (26 and 27). The digital broadcast signal demodulation section (28) includes a logical section (33-2) that sets a gain of the variable gain amplifier to have a minimum value if the channel selection section selects the analog broadcasting.

摘要： A tuner includes, in part, one or mixers, one or more filters, one or more variable gain stages, one or more analog to digital converters, and a baseband processor. Each filter is responsive to an associated mixer's output signal. Each variable gain stage is responsive to an associated filter's output. Each analog-to-digital converter is adapted to convert the output signal of an associated variable gain stage to a digital signal. The baseband processor is responsive to the digital signal supplied by the analog-to-digital converter(s). The baseband processor is further configured to supply a signal to be demodulated by a processing unit external to the integrated circuit. The baseband processor performs no or a fraction of the required demodulation functions. The processing unit may be a central processing unit or a graphical processing unit.

摘要： In a terrestrial mode of a TV having analog and digital capability, the RF gain is controlled using the TV's IF tuner (16) output. In a digital cable mode the RF gain is controlled using the output of the TV's IF SAW filter (36), and in an analog cable mode the RF gain is controlled using the output of an analog demodulator (32).

摘要： A single conversion tuner suitable for receiving RF signals having different requirements as to selectivity, linearity and image rejection is presented. Tuners of this kind are particularly useful for digital terrestrial as well as cable reception, where different modulation schemes require very high image rejection ratios on one hand and high linearity or pass band flatness on the other hand. The inventive tuner features a double-tuned tuneable filter in combination with an image reject mixer. The double-tuned filter provides excellent pass band flatness, while the image reject mixer provides a high intrinsic image rejection. The image rejection ratio of the combination of image reject mixer and tuneable filter is very high and fulfils the requirements of commonly used modulation schemes such as 8VSB, while the pass band flatness is compliant with the requirements for modulation schemes such as QAM.
摘要翻译：提出了适用于接收对于选择性，线性和镜像抑制具有不同要求的RF信号的单个转换调谐器。这种调谐器对于数字地面和电缆接收特别有用，其中不同的调制方案一方面需要非常高的图像抑制比，另一方面要求高线性度或通带平坦度。本发明的调谐器具有与图像拒绝混合器组合的双调谐可调滤波器。双调谐滤波器提供优异的通带平坦度，而图像抑制混频器提供高内在的图像抑制。图像抑制混频器和可调滤波器组合的图像抑制比非常高，满足了常用调制方案（如8VSB）的要求，而通带平坦度符合QAM等调制方案的要求。
