A research team led by Prof. Tian-Bao Ma from the Department of Mechanical Engineering at Tsinghua University has proposed a ...

A digital pulsed modulation for high efficiency and linearity, switched-mode PA is proposed. Based on Digital Outphasing Exponential Modulation, the paper shows the underlying concept and simulations ...

In this study, an ion-funnel-integrated photoionization (IFPI) source was developed. Following a systematic investigation of the effects of radio frequency (RF) amplitude on the ion transmission ...

In this paper, a new approach for visual attention selection called amplitude modulation Fourier transform is proposed, which is based on two up-to-date works: spectral residual model (SR) and phase ...
