【正文】 波、高通濾波及帶通濾波電路，本設(shè)計是基于二階帶通濾波電路的一個中心頻率為10KHZ的濾波電路。 關(guān)鍵字:遲滯比較器；二階無線增益帶通濾波電路；中心頻率Abstract Square wave generator in the science and engineering experiment has wide application, and at the same time in the life of the digital equipment, home appliances, electronic toys, and many other areas also have demand. Square wave signal is a kind of application of the signal, it is widely in scientific research, engineering education and the use of the production practice and is very popular. It is usually used as standard signal, used in electronic circuit performance test or parameter measurement. In addition, in many tester are required in the standard square wave signal detection some physical quantities. Produced by square wave circuit can hysteresit parator and R C, basic circuit structure, by 555 the timer add some resistance, capacitance of a peripheral device. Filter circuit is also in electronic circuits also have larger applications, such as people tend to get a specific frequency of the signal, but the actual input contains various frequency signal, would then use with the corresponding filter circuit to filter the frequency of the signal don39。t need and keep that people want to frequency signal. Constitute the filter circuit with low pass filter highpass filter, and bandpass filter circuit, the design is based on secondorder bandpass filter circuit of a center frequency for 10 KHZ filter circuit.Key words: hysteresit parator。 Second order wireless gain bandpass filters circuit。 Center frequency第一章 緒論 設(shè)計目的由于在課堂上學(xué)習(xí)的都是一些純粹的理論知識，沒有在實踐中得到檢驗，始終無法令人信服。本設(shè)計基于對濾波電路的基礎(chǔ)上對信號處理做了一個簡單大設(shè)計，可實現(xiàn)當輸入一個方波時，輸出同頻率的正弦波，完成方波到正弦波的轉(zhuǎn)化，通過設(shè)計可以將所學(xué)的電子技術(shù)知識運用到實際上，加深對濾波電路、方波產(chǎn)生電路的理解，鍛煉自己的動手能力，培養(yǎng)團隊合作精神。 設(shè)計內(nèi)容（1） 了解信號波形的產(chǎn)生于濾波電路的基本原理；（2） 完成信號波形的產(chǎn)生與濾波電路（設(shè)計并分析計算單元電路，對元器件進行選型）；（3） 繪制信號波形的產(chǎn)生與濾波電路電路圖；（4） 組裝調(diào)試濾波電路；（5） 進行實物檢查，設(shè)計答辯并完成設(shè)計報告； 設(shè)計要求（1） 設(shè)計遲滯比較器方波產(chǎn)生電路，頻率為10KHZ可調(diào)；（2） 設(shè)計一個有源濾波器，經(jīng)濾波電路得到的正弦信號幅度峰峰值達到6V以上；（3） 設(shè)計2個雙電源電路：正負5V和正負12V； 設(shè)計進度安排此報告將按照如下思路進行展開描述：第一章主要介紹系統(tǒng)的總體設(shè)計與方案的論證；第二章主要介紹各單元模塊的電路設(shè)計與相關(guān)參數(shù)的分析計算；第三章重點介紹個單元模塊的調(diào)試、仿真及相關(guān)的分析、結(jié)論；最后是總結(jié)和有關(guān)的參考文獻。第2章 系統(tǒng)總體設(shè)計 方案的設(shè)計與選擇 （1） 方波產(chǎn)生電路 方案一：用MAX0832集成芯片產(chǎn)生所需的方波，可靠性好，穩(wěn)定性好，但經(jīng)
