接收通带 [jiē shōu tōng dài]
received passband
- 摘要采用巴特沃思型和贝塞尔函数型2种方法进行接收机带通滤波器设计，借助EDA对该滤波器进行波特图和群延迟特性的比较。
Butterworth-type and Bessel function-type two ways are used for design of Bandpass filter for receiver, and with the help of EDA simulation tools, the bold plot and the group delay characteristics of the filters designed are compared. - 摘要分析了基于软件无线电的宽带数字中频接收机中的关键技术－带通采样下变频技术、数字下变频技术、多速率处理技术，并实现了欠采样技术条件的软件系统仿真。
This paper discusses key technology in the digital intermediate frequency receiver with wide band based on software radio, including down-converter on condition of band-pass-sampling, digital down-converter, multi-rate digital signal processing, band-pass signal decimating, and achieves software system simulation based on under-sampling. - 未来可能会出现用户可编程数字滤波系数的带通ΣΔADC，这样接收机的通频带就可以随着所接收的信号的特性而改变。
In the future it may be possible to have such bandpass sigmadelta ADCs with userprogrammable digital filter coefficients, so that the passband of a receiver could be modified during operation in response to the characteristics of the signal (and the interference!
