在改进

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.

CMA, as an alternate deicer, tends to inhibit corrosion and appears to be relatively harmless to the environment. But CMA is expensive because of the high price of its material, and it has less ability in melting ice than sodium chloride. Besides these, CMA sticks to wet surfaces and can congeal to form hard chunks, difficult to store for a long time, dusty and a strong vinegar smell when spread.

而CMA是对氯化物盐除冰剂的重大改进，CMA具有无污染，环保的特点，对金属几乎无腐蚀，但由于原料价格昂贵，使得CMA的价格不菲，CMA对冰的融化能力不如氯化钠，CMA易结块，不宜长期储藏，在撒布时形成的粉尘及刺鼻的酸味亦是需要改进的地方。
