On the basis of high speed hybrid filter banks adc system, a kind of downsampler model based on bandpass sampling theorem is presented, and analyzed, proved in time and frequency domain, in addition a downsampler is designed according to the model. a class of high effective hybrid filter banks adc system which bases on the downsampler and radio frequency spectrum is proposed, of which digital signal rate falls m times as fast as the former
作者提出了一種基於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抽取器，進而根據無線電射頻信號頻譜的特點，提出了高效混合濾波器組adc系統，其數字信號輸出速率比高速混合濾波器組adc系統降低m - 1倍。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。
