軍用晶體濾波器介紹濾波是對于信號處理的比較重要的一個概念，它一般分為兩種，一種是經典濾波，還有一種則是現代濾波。下來一起跟軍用晶體濾波器簡單的了解一下吧。

首先我們(men)先來簡單的(de)(de)(de)(de)了解一(yi)下經典濾(lv)(lv)波(bo)(bo)(bo)(bo)的(de)(de)(de)(de)概(gai)念。軍用(yong)(yong)晶(jing)體(ti)濾(lv)(lv)波(bo)(bo)(bo)(bo)器介(jie)紹經典濾(lv)(lv)波(bo)(bo)(bo)(bo)是(shi)(shi)(shi)根據(ju)(ju)傅立(li)葉分(fen)(fen)析(xi)和變換提出的(de)(de)(de)(de)一(yi)個工程(cheng)概(gai)念。根據(ju)(ju)高等數學(xue)理論，任何一(yi)個滿足一(yi)定條件的(de)(de)(de)(de)信(xin)(xin)號(hao)(hao)(hao)，都(dou)可(ke)以被看成(cheng)(cheng)(cheng)是(shi)(shi)(shi)由無限個正(zheng)弦(xian)波(bo)(bo)(bo)(bo)疊(die)加而成(cheng)(cheng)(cheng)。簡單說來就是(shi)(shi)(shi)工程(cheng)信(xin)(xin)號(hao)(hao)(hao)是(shi)(shi)(shi)不(bu)(bu)同(tong)頻(pin)(pin)(pin)率(lv)(lv)(lv)的(de)(de)(de)(de)正(zheng)弦(xian)波(bo)(bo)(bo)(bo)線(xian)性疊(die)加而成(cheng)(cheng)(cheng)的(de)(de)(de)(de)，組成(cheng)(cheng)(cheng)信(xin)(xin)號(hao)(hao)(hao)的(de)(de)(de)(de)不(bu)(bu)同(tong)頻(pin)(pin)(pin)率(lv)(lv)(lv)的(de)(de)(de)(de)正(zheng)弦(xian)波(bo)(bo)(bo)(bo)叫做(zuo)信(xin)(xin)號(hao)(hao)(hao)的(de)(de)(de)(de)頻(pin)(pin)(pin)率(lv)(lv)(lv)成(cheng)(cheng)(cheng)分(fen)(fen)或叫做(zuo)諧波(bo)(bo)(bo)(bo)成(cheng)(cheng)(cheng)分(fen)(fen)。軍用(yong)(yong)晶(jing)體(ti)濾(lv)(lv)波(bo)(bo)(bo)(bo)器介(jie)紹只允(yun)許一(yi)定頻(pin)(pin)(pin)率(lv)(lv)(lv)范(fan)圍內的(de)(de)(de)(de)信(xin)(xin)號(hao)(hao)(hao)成(cheng)(cheng)(cheng)分(fen)(fen)正(zheng)常通過，而阻止另一(yi)部分(fen)(fen)頻(pin)(pin)(pin)率(lv)(lv)(lv)成(cheng)(cheng)(cheng)分(fen)(fen)通過的(de)(de)(de)(de)電(dian)路，叫做(zuo)經典濾(lv)(lv)波(bo)(bo)(bo)(bo)器或濾(lv)(lv)波(bo)(bo)(bo)(bo)電(dian)路。用(yong)(yong)模擬電(dian)子電(dian)路對(dui)模擬信(xin)(xin)號(hao)(hao)(hao)進行(xing)濾(lv)(lv)波(bo)(bo)(bo)(bo)，其基本原理就是(shi)(shi)(shi)利用(yong)(yong)電(dian)路的(de)(de)(de)(de)頻(pin)(pin)(pin)率(lv)(lv)(lv)特(te)性實(shi)現對(dui)信(xin)(xin)號(hao)(hao)(hao)中頻(pin)(pin)(pin)率(lv)(lv)(lv)成(cheng)(cheng)(cheng)分(fen)(fen)的(de)(de)(de)(de)選(xuan)擇。根據(ju)(ju)頻(pin)(pin)(pin)率(lv)(lv)(lv)濾(lv)(lv)波(bo)(bo)(bo)(bo)時，是(shi)(shi)(shi)把(ba)信(xin)(xin)號(hao)(hao)(hao)看成(cheng)(cheng)(cheng)是(shi)(shi)(shi)由不(bu)(bu)同(tong)頻(pin)(pin)(pin)率(lv)(lv)(lv)正(zheng)弦(xian)波(bo)(bo)(bo)(bo)疊(die)加而成(cheng)(cheng)(cheng)的(de)(de)(de)(de)模擬信(xin)(xin)號(hao)(hao)(hao)，通過選(xuan)擇不(bu)(bu)同(tong)的(de)(de)(de)(de)頻(pin)(pin)(pin)率(lv)(lv)(lv)成(cheng)(cheng)(cheng)分(fen)(fen)來實(shi)現信(xin)(xin)號(hao)(hao)(hao)濾(lv)(lv)波(bo)(bo)(bo)(bo)。
