SRC in SDR is also discussed, and two improved structures of CIC filter are presented. The first one is a CIC decimation filter based on polyphase structure and partially sharpening technique, which is suitable for the situation where the requirements in passband attenuation is not very high while the requirements in alias suppression and operating speed are relatively high. The other one is an improved CIC-Rotated Sinc decimator which possesses improved frequency response, low operating rate and low cost in hardware as well.

The existing system digitizes the IF signal at the output of the intermediate frequency amplifier by using a 40MSPS A/D converter and improves the real-time ability of the system with the help of high-speed DSP and high-speed local bus.

现有系统从辐射计的中频输出直接进行采样速率为40MSPS的A/D转换，并采用高速DSP和高速局部总线来提高系统实时性。

The results shoed that after spraying 1 and 5 mgL^(-1) of anthraquinones, the photosynthetic rate raised by 38.03% and 39.73%, chlorophyll content increased by 3.53% and 3.83%, and MDA content decreased by 11% and 23%, respectively. The anthraquinones could absorb solar UV radiation, and convert the harmful UV into blue or yellow light which can promote plant photosynthesis. It as suggested that foliar-spraying appropriate concentrations of aloe's anthraquinones could promote wheat photosynthetic activity, alleviate UV harm, and thus, increase wheat yield.
