在电子系统没计中,标准起着举足轻重的作用。这种作用在通信系统中尤为重要。例如,对通信系统来说,信号源和接收设备在物理层、数据格式和协议层方面都必须遵守各方协商、一致同意的标准,以便传输数据。但是,标准不是加速人们对产品的认可,就是阻碍产品的技术创新。例如,蜂窝电话市场中可能有一种或几种标准,这取决于你所在的地 Not counting in the electronic system, the standard plays a decisive role. This role is especially important in communications systems. For example, for communication systems, signal sources and receiving equipment must adhere to negotiated and agreed upon standards at the physical, data and protocol layers for the transmission of data. However, the standard is not to speed up people’s acceptance of the product, or hinder the technological innovation of the product. For example, there may be one or more standards in the cellular phone market, depending on where you are
