1·For bandpass signal under digital quadrature sampling, there is spectrum shifting. Although the sampling frequency satisfies the sampling theorem, it may cause spectrum aliasing.
在数字正交采样中，带通信号存在频谱迁移问题，虽然满足带通信号的采样定理，仍可能产生频谱混叠。
2·Spectra aliasing formula is obtained in theory and the method of spectra revision is proposed. Simulation results show that this method is simple and effective.
从理论上导出了光谱混叠公式，并提出了光谱修正方法，仿真实验结果表明该方法简单有效。
3·As for struct padding and aliasing, the compiler vendor has likely implicitly assumed that only their compiler is to be used.
至于结构填充和混叠，编译器厂商可能已经隐含地假定只有他们的编译器将被使用。
4·In addition, line mode and zero-mode voltage wave cross each other at the point of fault which causes the natural frequency "aliasing".
此外，故障电压行波于非对称短路点发生线模与零模行波相互交叉透射，致使故障电压自然频率“混叠”。
5·The paper presents a discussion on the aliasing for sampled imaging system.
文章就采样成像系统中的混叠问题进行了探讨。
