Abstract: PURPOSE: A method for automatically measuring a digital broadcasting tuner is provided to perform frequency error connection according to an operation environment accurately and automatically. CONSTITUTION: Initialization for frequency mapping is performed to measure frequency characteristic according to frequency tuning voltage of a tracking filter of each frequency band using a pre-stage of a double frequency conversion tuner(901).

Abstract: PURPOSE: A digital television tuner of automatically selecting channel of wide band frequency using a look up table and a microprocessor is provided to suppress an interference signal which deteriorate an image quality of TV channel or induce a broadcasting impossible state. CONSTITUTION: The digital television tuner of automatically selection of channel of wide band frequency using a look up table and a microprocessor includes following units. A tuner microprocessor(313) forms an interface with the frequency channel selection information induced by the outside IIC-BUS signal. The respective frequency characteristics of divided bandwidths according to the tuning voltage of a tracking filter are measured and then the look-up table is stored to the ROM(Read Only Memory)(314). Thereafter, when the IIC-BUS signal included frequency information is applied to the microprocessor, the processor transmits the same frequency information to a phase synchronization loop and the ROM. A tracking filter data in which its frequency characteristic is the same as that of the voltage control generator is read among the data values stored to the ROM and transmitted to a 14 bit D/A(Path b,315). The D/A outputs an analog value corresponding to the transmitted data and transmits to an OP AMP(316). The analog value is changed into a constant DC value through a low pass filter(317) and then a frequency tuning voltage of the tracking filter is provided.
