高通濾波器-
We design the qmf based on the criteria of minimum frequency bandwidth and the qmf that possess linear phase, and give a example of a signal decomposed and restructured. 4. in the research of channel dropping filters, we use 5 rank butterworth filter to approach the digital filter. we design lc unpower netwok and rc power network. we manufacture lc lowpass and highpass filter ， and test their performance ; we simulate the appliance of the channel dropping filters in the system
4 .在頻帶分割濾波器的設計方法中，用5階巴特沃斯濾波器逼近最小頻寬正交鏡像濾波器，對無源和有源濾波器進行了模擬設計；設計並製作了無源lc低通和高通濾波器，測試了它們的性能；並對分割濾波器在系統中的應用進行了計算機模擬。 -
It can accomplish the contrast reverse transformation, contrast linear enhancement, histogram modification, filter ( lowpass and highpass ), and the writer give two new algorithms which has been realized in fpga, one is automatic gain linear enhancement, the other is complicated background restrain based on common knowledge
其核心部分採用altera公司的ep1k100qc208晶元，構造專用處理功能，實現了直方圖統計與均衡化、高通濾波、 fir濾波、中值濾波等演算法。同時提出了自動增益線性變換、基於知識的紅外背景抑制二種新演算法，並在fpga中實現。 -
