A filter is widely used in overall RF system. There are many species and structures in filter. A filter seems to be simple, but there are many considerations to design filter. In this paper, we design microstrip bandpassfilter which has bandwidth of 500 MHz and center frequency of 2.5 GHz. Alumina is used as substrate, and chromium is used as conductor. Final results are achieved as follows. Ins

비디오 필터는 Post-Detection 필터(잡음 평균화 필터;Noise Averaging Filter)로 사용하며, 주 목적은 화면에 표시된 스펙트럼의 잡음을 평균화하여 감소시키고, 따라서 아주 작은 신호를 인식하기 쉽도록 하여준다. 이 비디오 필터를 사용하기 전에는 주의가 필요하다.
