在射频前端模块中,射频滤波器起着至关重要的作用。它可以将带外干扰和噪声滤除以以满足射频系统和通讯协议对于信噪比的需求。
lc滤波器有多种,做仪器设备中常用到的是电源滤波器和信号滤波器.滤波器的选择需要考虑那些呢,看国创总结!
军工电源目前在市场已经很常见了,正逐渐趋向大众化,主要适用的群体主要是通信领域,交通,航空航海,电台、雷达、航空、航天、航海、舰艇,加工工业等.近年来,国家政府大力发展电力行业,其中军用电源主要向适应性更强,隐蔽性更好。
理想滤波器的特性只需用截止频率描述,而实际滤波器的特性曲线无明显的转折点,两截止频率之间的幅频特性也非常数,故需用更多参数来描述。看看国创总结的实际滤波器的基本参数!
dvi分配器一分四此款dvi分配器为多端口数字视频输出的信号分配器,具有一路dvi视频输入,多路dvi视频输出。在多媒体应用系统中,往往需要多个数字显示终端显示同一dvi信号源的画面。如果为每一显示终端配置个dvi信号源,这样既增加了系统成本,又大大降低了系统的可靠性。
