Digital frontend design for three-bands aliasing RF signals

open access: yesDianzi Jishu Yingyong, 2019
In order to solve the problem of three-band bandpass signal aliasing, a delay-adjustable third-order bandpass sampling structure is proposed. By designing a digital anti-aliasing filter, the alias-free reception of three-band bandpass signals can be ...
