Examples
- 2 . using multilevel high frequency and mid frequency narrowband filter , so as to dispel any possible interfering signals
1 .采用进口元件装配2 .可分频的最大为40频点 - With the great development of radar and microwave technology , it ' s necessary to increase switching time of mid frequency switch under the condition of high isolation and low insertion loss
随着雷达以及微波技术的发展，对中频开关的性能提出了越来越高的要求，主要是在高隔离度，低损耗的前提下，提高开关速度。 - In order to exert the speed performance of gaas mid frequency switch and improve the agility to be compatible with ttl control electric level of most present system , we studied the gaas mid frequency switch with ttl driver
为了充分发挥gaas开关的速度性能，提高gaas微波开关的使用灵活性，以及与目前多数系统中的开关ttl控制电平相兼容，我们对ttl电平驱动器的gaas中频开关进行研究。 - As for frequency domain , tirls includes mainly 3 frequency bands : ( 1 ) high frequency band with period less than 1 year , which is relative to weather ; ( 2 ) mid frequency band with predominant period 1 year , relative to sun , plant and season ; ( 3 ) low frequency band with period more than 1 year , relative to the crustal activity and long period variation of atmosphere temperature
从频率域看，地表热红外辐射主要存在3种频段： ( l )高频，周期小于1年的天气变化； ( 2 )中频，以1年周期为主的太阳、植被与季节变化； ( 3 )低频，大于1年周期的大气变化的长周期成份，地壳缓慢的运动引起的热辐射变化亦属于长周期变化。 - The control of the spatial mid frequency wavefront distortion was achieved based on our cri wavefront sensing and lctv wavefront correcting system . the results of our research show that crs interferometer can be used to diagnosing the mid and low frequency wavefront distortion of a laser beam and lcslm can be used to availably controlled it
