heterodyne filter meaning in English
外差滤波器
外差式滤波器
Examples
- Digital adaptive heterodyne filter adopts the heterodyne - modulation conception , which makes the filter work in low frequency and lessens the complexity of design
数字自适应外差滤波器运用外差调制的概念，使滤波在低频率处操作，从而降低了滤波器的复杂程度。 - According to the characteristic of digital adaptive heterodyne filter and the conception of interference counteraction , the paper presents a new structure to enable the filter track the interference signal precisely and control the width and depth of notch . through simulation , it is demonstrated that the new structure can suppress one or more interference signals and the filtering operation has little influence on signal spectrum
论文利用数字自适应外差滤波器的特点，运用干扰抵消的概念，提出了一种新的结构，能使滤波器精确跟踪干扰信号，并能控制陷波的宽度和深度，经仿真验证，该结构的滤波器能较好的抑制一个和多个干扰，同时滤除干扰后对信号频谱的损害较小。
