...James Deng; Jianbin Gao; Qi Xia; Jianping Li; Mao Ye Purpose The purpose of this paper is to present a symmetrical method to extract smooth signal from linear mixtures in the frequency domain; with experimentations, the method is thereafter evaluated. Design/methodology/approach The Second...

...James Deng; Yuanwang Yang; Jingye Cai; Jose Schutt‐Aine Purpose Spurious frequencies (spurs) resulting from phase truncation are one of the main signal integrity issues for direct digital synthesizers (DDS). The standard approach in DDS design consists of truncating the phase word output from...

... presents the effects of the shielding box on the dispersion properties of the microstrip lines. Both the measured results and the theory analysis are given in a wide‐frequency range and the structures of the test fixture are also illustrated in detail. © Emerald Group Publishing Limited 2010...

...TianQuan James Deng; Lijuan Wu; Zehong Li; Bo Zhang; Zhaoji Li Purpose The purpose of this paper is to present a novel n‐buried partial silicon‐on‐nothing (SON) structure of radio frequencies (RF) power lateral double‐diffused metal‐oxide‐semiconductor (LDMOS) and analyze its RF characteristics...

...Berardi Sensale Rodriguez; Berardi Sensale Cozzano Purpose The purpose of this paper is to introduce a fast and simple method to calculate an estimation of parameters of interest of microstrip antennas, such as the resonance frequencies for example. Design/methodology/approach The Trefftz...

...L. Unsworth The problem of determining a rational function whose magnitude characteristic approximates some arbitrary functions of frequency in an equiripple sense is discussed. A novel method that provides a rational all‐pole equiripple approximation to any arbitrary magnitude response...
