轉換后帶寬 的英文怎麼說
中文拼音 [zhuǎnhuànhòudàikuān]
轉換后帶寬
英文
post conversion bandwidth-
The bottleneck of hybrid filter banks adc system is that it cannot sample directly higher radio frequency signal because of lower analog input bandwidth of its adc. in order to remove it, a kind of downsampler model based on nyquist and bandpass sampling theorem is presented, analyzed and proved in time and frequency domain, in addition a downsampler is designed according to the model. on the basis of hybrid filter banks adc system, a class of high speed hybrid filter banks adc system is proposed
針對混合濾波器組adc系統因其adc模擬輸入帶寬低而不能對頻率較高的射頻模擬信號進行模/數轉換的瓶頸，作者提出了一種基於nyquist采樣定理和帶通采樣定理的抽取器數學模型，對該數學模型進行了時域、頻域的分析證明后，設計了一種基於該數學模型的sha抽取器，進而在混合濾波器組adc系統的基礎上，提出了高速混合濾波器組adc系統。Its basic function is to pick up the narrowband signals from the broadband & high speed digital signals, and transform it to the baseband. then the low speed baseband signals are sent to the following dsps for processing
其基本功能是從輸入的寬帶高速的數字信號中提取所需的窄帶信號，將其下變頻為數字基帶信號，並轉換成較低的數據率，以供后續的dsp作進一步的處理。
