摘　　要：利用分立元器件设计能够输出正弦波、方波和三角波的函数信号发生器。函数信号发生器产生的正弦波频率和幅度可调,并通过电压比较器将正弦波转化为方波,同时利用外加电压偏置的方式改变方波的占空比,利用积分电路将方波转换为三角波。在Multisim 11.0软件环境下进行函数信号发生器的电路设计及调试,仿真结果表明电路输出性能与指标达到设计要求。Discrete components are used in the design of function signal generator to generate sinusoidal wave, square wave and triangular wave.Frequency and amplitude of sinusoidal wave is generated adjustably.Vohage comparator is used to con- vert sinusoidal wave to square wave.The duty ratio of square wave is adjusted with the extra voltage bias.Integrating circuit is used in the transfer of square wave to triangular wave.System design and silnulation of the signal generator are completed u- sing Muhisim 11.0.Simulation results show that the output performance meet the design requirement.
