摘要： An improved method for forming a timbre sample (Q sample) is described. A first Q sample is extracted. A fixed length of the first Q sample is extracted to form a first QL. A portion of the first Q sample other than the first QL is treated as a first pre-waveform. A last portion of the first pre-waveform is extracted and is processed with the second Q sample by a first COS modulation so as to obtain a second QL, which is connected to the first pre-waveform to form a second Q sample. A first period waveform of the second QL and a last portion of the first pre-waveform are processed by a second COS modulation to form a single period QL. Repeating the single period QL forms a third QL. Connecting the third QL to the first pre-waveform forms a third Q sample. The second QL is transformed by a digital Fourier transformation, and its high frequency modes are removed. The transformed second QL is inversely transformed back by an inverse digital Fourier transformation to form a fourth QL. Adding the third QL and the fourth QL forms a fifth WL sample, which power is properly normalized. A second pre-waveform is obtained by repeating the sixth QL. The first and second of pre-waveforms are processed by a linear cross fading algorithm to form a third pre-waveform. The third pre-waveform and the sixth QL are connected together to obtain an improved Q sample.

摘要： An light emitting diode (LED) control, a plurality of duty cycle signals corresponding to a plurality of LEDs are stored in a dual-port memory by memory mapping. By sampling, the stored duty cycle signals are outputted to generate a plurality of parallel single-bit data each having one single bit. After the single-bit data are converted by a data transmission module, each bit of the single-bit data is serially outputted to a drive module to drive the LEDs. Thus, the ON duty cycles of the LEDs are modulated by pulse width modulation (PWM), light emitted from the LEDs are mixed in time-domain, and the brightness of the LEDs can be controlled.
