The reference level for the relative attenuation arel of the TFS 150AH is the minimum of the pass band attenuation amin. The minimum of the pass band
attenuation amin is defined as the insertion loss ae. The centre frequency fc is the arithmetic mean value of the upper and lower frequencies at the 3 dB
filter attenuation level relative to the insertion loss ae. The temperature coefficient of frequency Tc
f
is valid for both the reference frequency fc and the
frequency response of the filter in the operating temperature range. The bandwidth change of the filter in the operating temperature range is included in the
production tolerance scheme.

语音作为自然的人机接口，可以使车载导航系统实现更安全、更人性化的操作。通过国内外车载导航系统的功能对比可知，支持语音交互是车载导航系统的一个发展趋势。另外，市场信息服务公司J.D Power and Associates的调研数据也表明，56％的消费者更倾向于选择声控的导航系统。因此，开发车载语音导航系统是很有意义的。目前，国内已经具备开发车载语音导航系统的技术基础，特别是文语转换TTS技术...[详细]
