PURPOSE: An analog/digital broadcasting receiving apparatus is provided to turn on a corresponding IF line by separating an analog IF line from a digital IF line at a rear portion of an MOPLL unit when selecting an analog broadcasting or digital broadcasting. CONSTITUTION: An MOPLL(Mixer Oscillator Phase Locked Loop) unit(110) converts an RF signal of a desirable channel into an IF(Intermediate Frequency) signal. A path selection unit(130) selectively outputs the IF signal through a digital channel or analog channel. An analog filter unit(150) blocks the IF signal of a preset specific frequency band in the IF signal. A demodulator(170) demodulates the digital IF signal of the path selection unit and the analog IF signal of the analog filter unit. |
