Analog TV signal receiving circuit for reducing signal distortion using equalizer configuring method
An analog television (TV) signal receiving circuit and method and an associated equalizer coefficient configuration apparatus and method are disclosed for correcting a distortion problem occurred in a reception process of an analog TV signal by configuring an equalizer in the analog TV signal receiving circuit. The analog TV signal receiving TV includes a tuner, an analog-to-digital converter (ADC), and a demodulator. The tuner receives an analog radio-frequency (RF) TV signal to generate an analog frequency down conversion signal. The ADC generates a digital frequency down conversion signal according to the analog frequency down conversion signal. The demodulator includes a front-end circuit for generating a digital demodulated signal according to the digital frequency down conversion signal, and an equalizer for generating a digital receiving signal according to the digital demodulated signal. The equalizer includes a plurality of correction coefficients that are generated according to a predetermined rule.
