大学本科生毕业设计（论文） Multisim是美国国家仪器（NI） 有限公司推出的以Windows为基础的仿真工具，适用于初级的模拟/数字电路板的设计工作，包含电路原理图图形及电路硬件描述语言的输入方式，具有丰富的仿真分析能力。 模拟乘法器是一种完成两个模拟信号（电压或电流）相乘作用的电子器件。它具有两个输入端对和一个输出端对，是三端对有源器件。 主要内容为基于Multisim的模拟乘法器应用设计与仿真。阐述了双边带调幅及普通调幅、同步检波、混频、乘积型鉴相电路的原理，并在电路设计与仿真平台Multisim11仿真环境中创建集成模拟乘法器MC1496电路模块，利用模拟乘法器MC1496完成各项电路的设计与仿真，并结合LabVIEW虚拟仪器实现对语音信号的普通调幅及解调。 关键词：Multisim；模拟乘法器 ；MC1496 Abstract Multisim introduced by United States National Instruments(NI) Limited company is a Windows-based simulation tool, suitable for design elementary analog / digital circuit, contains a circuit theory of diagram and the circuit hardware description language input methods, with extensive simulation analysis. Analog multiplier is a complete two analog signals (voltage or current) multiplied by the role of electronic devices. It has two inputs and one output on the right, yes three-terminal on the active device. The main content is that analog multiplier multisim-based application design and simulation. Describe some circuit’s theory, such as Double Side Band amplitude modulation and common amplitude modulation、synchronous detection、mixing、product type phase. Create the integrated circuit analog multiplier MC1496 module in simulation platform Multisim11 simulation environment, make use of the analog multiplier MC1496 module complete circuit design and simulation, combined with labVIEW fictitious instrument to complete the speech signal amplitude modulation and demodulation. ??Keywords: Multisim;Analog Multiplier;MC1496 PAGE 28 目 录 TOC \o 1-2 \h \z \u HYPERLINK \l _Toc264913121 第1章 概述 PAGEREF _Toc264913121 \h 1 HYPERLINK \l _Toc264913122 1.1 Multisim简介 PAGEREF _Toc264913122 \h 1 HYPERLINK \l _Toc264913123 1.2 Multisim发展 PAGEREF _Toc264913123 \h 1 HYPERLINK \l _Toc264913124 第2章 总体设计思想 PAGEREF _Toc264913124 \h 3 HYPERLINK \l _Toc264913125 2.1 模拟乘法器MC1496的工作原理 PAGEREF _Toc264913125 \h 3 HYPERLINK \l _Toc264913126 2.2 幅度调制 PAGEREF _Toc264913126 \h 5 HYPERLINK \l _Toc264913127 2.3 同步检波 PAGE
