1 系統功能 本系統擬定對頻率范圍在1~50 kHz左右的TTL電平脈沖序列進行多路延遲處理。各路延遲時間分別由單片機動態設定，最大延遲時間為1 ms，最大分辨率為0.15 ns級。 3 方案實現 系統選用Actel公司的ProASIC3 A3P250芯片實現數字部分。系統時鐘由外部50 MHz晶振提供，時鐘引腳連接到FPGA的CCC全局時鐘引腳上；頻率可以通過FPGA內部的PLL實現倍頻和分頻，設定需要的頻率。由于在多路脈沖延遲方案中電路的同步是保證控制正確的條件，所以應該首先為電路提供一個基準脈沖。

The 4.0 kbit/s speech codec described in this paper is based on a Frequency Domain Interpolative (FDI) coding technique, which belongs to the class of prototype waveform Interpolation (PWI) coding techniques. The codec also has an integrated voice activity detector (VAD) and a noise reduction capability. The input signal is subjected to LPC analysis and the prediction residual is separated into a slowly evolving waveform (SEW) and a rapidly evolving waveform (REW) components. The SEW magnitude component is quantized using a hierarchical predictive vector quantization approach. The REW magnitude is quantized using a gain and a sub-band based shape. SEW and REW phases are derived at the decoder using a phase model, based on a transmitted measure of voice periodicity. The spectral (LSP) parameters are quantized using a combination of scalar and vector quantizers. The 4.0 kbits/s coder has an algorithmic delay of 60 ms and an estimated floating point complexity of 21.5 MIPS. The performance of this coder has been evaluated using in-house MOS tests under various conditions such as background noise. channel errors, self-tandem. and DTX mode of operation, and has been shown to be statistically equivalent to ITU-T (3.729 8 kbps codec across all conditions tested.
