基于EWB的555多谐振荡器设计研究

he paper introduces harmonic oscillator 555 and many of the concepts, from the Angle of the theory and practice of the circuits more harmonic oscillator 555 composed and design principle and the vibration frequency calculation is analyzed and summarized, and according to the present situation of the application of electronic design automation, using electronic simulation software EWB, improve the working platform for electronic circuit design of experiment, Through more than harmonic oscillator 555 design example of using electronic simulation software EWB, the simulation validation. For the more harmonic oscillator 555 composed of changing parameters, and vibration of electronic voltage waveform, oscillation process and intermittent oscillation observed, analysis and test, deepen the understanding of the working principle of circuit. Software EWB explained in practical application and digital circuit design and logical in superiority. [2
