Abstract
In a card-type electronic tuner, a digital broadcasting is received without need of hardware reconstruction of a personal computer used for the digital broadcasting reception. The electronic tuner includes a signal input terminal, a local oscillator, a mixer, an output terminal, a PLL circuit and a data input terminal. All of these components are packaged in a card-type case. A digital signal processor includes a digital signal extractor and/or an A/D converter and is connected between the mixer and the output terminal. The digital broadcasting is received and the data is applied directly to the personal computer. The electronic tuner in the shape of a card can be used with an expansion slot for a memory card of the personal computer and there is no need of reconstructing a hardware of the personal computer.
