One of the advantages of direct frequency synthesis technique (e.g., flying-adder architecture) is its capability of generating arbitrary frequency by utilizing the time-average-frequency concept. In the clock output of the direct frequency synthesizer, instead of one type of cycle, there are two types of cycles. Unlike the conventional one-type-cycle clock wherein clock energy is concentrated at its designed frequency, Time-Average-Frequency based clock spreads some of its energy into spurious tones, which could be harmful to certain applications. The spurious tones are caused by the periodic carry sequence generated from a fractional part accumulator inside the frequency synthesizer. The invention suggests a method and an apparatus to break this periodicity and convert the spurious tones into broadband noise.

A method for reducing resonance energy of an LCD panel includes providing a plurality of driving signal patterns, each defining a non-overlap area width of a synchronization signal and a scan-line charging frequency, and determining an order of the plurality of driving signal patterns to modulate driving signals of the LCD panel accordingly.

A power-saving control circuit and method suitable for circuits including a first-in-first-out (FIFO) register is provided. In the present invention, a logic circuit is disposed between two circuit modules with data transmitted in between. When there is data input into the FIFO register, the logic circuit activates a clock signal of the circuit module in the receiving end for reading the data. When all the data stored in the FIFO register is read, the clock signal is turned off so that the power consumed by the clock signal is reduced without affecting the data transmitting efficiency and the purpose of power-saving is achieved.
