3) base band modulation
基带调制
1.
In WCDMA system,downlink base band modulation involves a lot of channels and complex functions,resulting in prolonged time and higher costs for test and verification.
WCDMA中下行链路基带调制信道多,功能复杂,对其测试和验证所花费的时间和费用也随之提高。
4) Base-band demodulation
制基带解调
5) bandpass∑△modulator
带通∑△调制器
1.
However, the speed of discrete-time bandpass∑△modulatorimplemented with switched-capacitor circuit is limited by the settling time of theopamps, while the continuous-time bandpass modulator can operate at much highsampling frequency, but suffers from the degradation of dynamic range due to thelow-Q LC or G_mC resonators.
在现代射频接收器中，要实现中频或射频数字化，必须有高速及高解析度的模／数转换器，带通∑△调制器被认为是满足这个要求的一个可能的候选。
6) baseband demodulator
基带解调器
1.
This paper puts forward the design method of DTV transposer using baseband demodulator as its core based on the analysis of its present status.
提出了以基带解调器为核心的数字电视转发器的设计方法。
补充资料：基带
基带(BASEBAnd)，又叫基频。在大部分手机中，基频都是最昂贵的半导体元件，随着TFT-LCD显示屏价格的下降，基频正在成为手机中占成本比例最高的元件。不仅如此，基频还决定了手机平台的选择，很大程度上决定了手机的功能和性能。毫无疑问，基频是手机的心脏。
