随着汽车的出现,人类的活动范围不断扩大:而移动电话的问世又缩短了人与人之间的距离。然而,当二者同时使用时所带来的不利影响是很明显的,来自世界权威机构的研究结果显示,驾车时如果以手持方式使用移动电话,会提高交通事故的概率。针对这个问题,有关主管部门正在制定相关法律法规予以规范。如果能够在车上安置一套完善的“车载免提通信系统”,则能明显加强行车的安全性!目前市场上的车载免提产品主要由高、中、低三个档次构成,高档产品有摩托罗拉系列产品。而一些低档产品更受到相当一部分车主的欢迎和喜爱。DSP数码化信号处理一般的车载免提通信系统在行车中都或多或少地存在着通话声音模糊,有杂音、飘
With the advent of cars, the range of human activities has been expanding: the advent of mobile phones has shortened the distance between people. However, when the two are used together, the adverse effects are obvious. Research from world authorities shows that using a mobile phone hand-held while driving can increase the probability of a traffic accident. In response to this issue, the competent authorities are formulating relevant laws and regulations to be regulated. If the car can be placed on a perfect set of “car hands-free communication system,” it can significantly enhance driving safety! Currently on the market car hands-free products mainly by the high, medium and low grades constitute the three, high-end products Motorola products. And some low-end products are more like a lot of car owners welcome and love. DSP digital signal processing General car hands-free communication system in the car are more or less there is a call voice blur, noise, floating
