Patent number: 8531309Abstract: A quantification indicating circuit includes an indicating lamp set, a converting circuit, and an indicating lamp control circuit. The indicating lamp set has a plurality of indicating lamps. The converting circuit has a plurality of predetermined threshold values which are compared with a numerical signal of a circuit board to generate a comparison result. The comparison result is converted to be outputs of a plurality of control bits. The indicating lamp control circuit is coupled between the indicating lamp set and the converting circuit and is used for controlling the number of the indicating lamps which are brightened according to the outputs of the control bits.Type: GrantFiled: May 11, 2012Date of Patent: September 10, 2013Assignee: ASUSTeK Computer Inc.Inventors: Bing-Min Lin, Chao-Chung Wu, Chin-Fu Ho

Analog TV signal receiving circuit for reducing signal distortion using equalizer configuring method
Patent number: 8525932Abstract: 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.Type: GrantFiled: August 24, 2011Date of Patent: September 3, 2013Assignee: MStar Semiconductor, Inc.Inventors: Ching Fu Lan, Wen Chieh Yang, Yi Hsuan Lai, Hsin Chuan Kuo, You Tsai Cheng, Chin Fu Ho, Jen Hsing Wang, Tai Lai Tung -
