摘要：本系統以icl8038集成塊為核心器件，制作一種函數信號發生器，制作成本較低。適合學生學習電子技術測量使用。icl8038是一種具有多種波形輸出的精密振蕩集成電路，只需要個別的外部元件就能產生從0.001Hz~30KlHz的低失真正弦波、三角波、矩形波等脈沖信號。輸出波形的頻率和占空比還可以由電流或電阻控制。另外由于該芯片具有調制信號輸入端，所以可以用來對低頻信號進行頻率調制。關鍵詞：函數信號發生器頻率調制Abstract：The system icl8038 integrated block as the core device，producing a kind of function signal generator，producing low cost.Suitable for students to learn the use of electronic technology measurement.icl8038 is a kind of multi-precision oscillator waveform output integrated circuits，a separate external components only need to be able to generate from the 0.001Hz ~30KHz low-distortion sine wave，triangle wave，square wave pulse signal，etc..Output waveform of the frequency and duty cycle can also be controlled by a currentor resistance.In addition，as the chip has a modulated signal input terminal，it can be used to low-frequency signal is frequency modulation.
