【正文】 circuit, it is often sinewave oscillation frequency of the oscillator circuit has a certain degree of stability, sometimes requires the oscillation frequency is very stable, as the radio munication system oscillation circuit, a digital system clock generating circuit. Nonsinusoidal in some electronic systems has bee increasingly wide range of applications, such as digital systems require a special signal, such as a square wave triangle wave ﹑are available through the nonsinusoidal wave generating circuit to get. In addition, various types of telemunications equipment and control systems, the filter wide range of applications。使用Multisim電路仿真軟件對其進(jìn)行仿真，用來驗證電路理論設(shè)計的正確性和可行性?；赥L082CD，本設(shè)計介紹了正弦波信號的產(chǎn)生，以及基于555定時器構(gòu)成的多諧振蕩電路的探究與設(shè)計。非正弦波在一些電子系統(tǒng)中有著日益廣泛的應(yīng)用，如數(shù)字系統(tǒng)需要的特殊信號，如方波﹑三角波都可以通過非正弦波產(chǎn)生電路來得到。畢 業(yè) 設(shè) 計（論 文）題 目： 信號處理電路的研究與設(shè)計 專 業(yè)： 電子信息工程 摘 要目前，信號產(chǎn)生與處理電路應(yīng)用非常廣泛。例如，在測量、遙控、通信、自動控制、和超聲波電焊等加工設(shè)備之中，都有正弦波振蕩器的應(yīng)用；在工程應(yīng)用中，例如在實驗用的低頻及高頻信號產(chǎn)生電路中，往往要求正弦波震蕩電路的震蕩頻率有一定的穩(wěn)定度，有時要求震蕩頻率十分穩(wěn)定，如通訊系統(tǒng)中的射頻振蕩電路、數(shù)字系統(tǒng)的時鐘產(chǎn)生電路等。此外，在電信裝備和各類控制系統(tǒng)中，濾波器應(yīng)用極為廣泛；濾波器的優(yōu)劣直接決定產(chǎn)品的優(yōu)劣，所以，對濾波器的研究和生產(chǎn)歷來為各國所重視。同時也介紹了信號處理的相關(guān)內(nèi)容，其中包括信號的疊加和二階有源濾波放大電路的探究與設(shè)計。關(guān)鍵詞：正弦波信號產(chǎn)生 方波信號產(chǎn)生 信號疊加 二階有源濾波放大 Abstract Currently, the signal generation and processing circuit is widely used. For example, in the measurement, remote control, munication, automatic control, and ultrasonic welding and other processing equipment into, has a sine wave oscillator is applied。 filter will directly determine the merits of products, so the research and production of the filter has always been valued by all countries. Based TL082CD, this design introduces the sine wave signal generation, and on the 555 timer consisting of multivibrator circuit inquiry and design. Also introduced the signal processing, including the signal superposition and secondorder active filter amplifier circuit of inquiry and design. Its use Multisim circuit simulation software simulation, circuit theory is used to verify
