摘要： 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.

摘要： A multi-band has as an elongated grounding plate disposed vertically with a top edge defined thereon. A simulation induction portion includes a first conduction strip extended obliquely from a substantial middle of the top edge and a second conduction strip extended along the top edge from a free end of the first conduction strip to form an obtuse angle between the first and second conduction strips. A connecting portion extends perpendicularly and opposite to the grounding plate from a free end of the second conduction strip. A feeding point disposes on the connecting portion, adjacent to the second conduction strip. A high frequency radiator and a low frequency radiator are extended opposite to each other from a free end of the connecting portion.

摘要： An antenna apparatus includes a housing defining a plurality of walls and a plurality of included angle spaces between the walls. An inner surface of one of the walls is configured a telecommunication antenna. One of the included angle spaces opposite to the wall on which the telecommunication antenna is configured a global positioning system antenna. A broadcast receiving antenna positions in the housing and between the telecommunication antenna and the global positioning system antenna. Because the telecommunication antenna and the global positioning system antenna position away from each other, the interference therebetween will be reduced.

摘要： A multi-band antenna includes a ground portion, a radiating element spaced from the ground portion, a tuning conductor extending from the radiating element and parallel to the ground portion to form a gap therebetween, a short-circuit conductor interconnecting the ground portion and the radiating element, and a feed point disposed at the radiating element and adjacent to the short-circuit conductor. The radiating element, the short-circuit conductor and the feed point function as a first inverted-F antenna obtaining a first high frequency band, and a second inverted-F antenna obtaining a low frequency band and a second high frequency band higher than the first high frequency band. The ground portion and the tuning conductor cause a capacitance effect to shift the second high frequency band to be close to the first high frequency band. It can cover various wireless communication frequency bands.
