Abstract: A method for driving a light source first sets a frame time and a unit time, and calculates the number of the unit time that the frame time can contain. Based on the turned-on duration (DTi) of a light-emitting device of the light source and the unit time, the turned-on numbers (Ni) and the compensation times (CTI) of the light-emitting devices are calculated. The light-emitting device is driven to emit a light beam according to the turned-on numbers (Ni) and the compensation times (CTI). The present driving method can be applied to light source and backing light source of liquid crystal displays.

Abstract: An impulsive noise suppresser and method thereof is provided. The impulsive noise suppresser includes an automatic gain control unit, variable gain amplification unit, impulsive detection unit and impulsive suppression unit. The automatic gain control unit determines a gain value according to a PAPR. The variable gain amplification unit amplifies a reception signal by the gain value.

The impulsive detection unit is coupled to the variable gain amplification unit for determining whether the amplified reception signal is larger than a maximum value of the predetermined range and outputting an impulsive alarm signal if the reception signal is larger than the maximum value. The impulsive suppression unit suppresses the impulsive noise as receiving the impulsive alarm signal, and then outputs an output signal.
