1) aliasing distortion
混叠失真
1.
In order to overcome this shortcoming,this paper proposes a design of novel subband filter banks the analysis filter and synthesis filter as a whole,using unconstrained quadratic optimization,let the synthesis filter banks match analysis filter banks,and separately suppress inband aliasing distortion in output signal.
为了克服这一缺点,通过一种新的子带滤波器组的设计方法,把分析综合滤波器作为一个整体,采用无约束二次优化方法,使综合滤波器组匹配分析滤波器组,在输出信号里单独抑制子带内的混叠失真。
2) aliasing distortion

1.
After analyzing some factors influencing the receiver performance,for example,noise factor,frequency conversion loss,dynamic range,isolation degree,mixing distortion.
从混频器的基本概念出发,分析了混频器设计中的关键技术,如噪声系数、变频损耗、动态范围、隔离度、混频失真等对接收机性能的影响,并从工程角度出发,指出在工程设计中应注意的要点。
