Design and Experiment of Digital Sine Wave Generator Based on PLD

One proposed a variety of digital sine wave generator of experimental teaching platform based on programable logic device (PLD).This experiment designed a digital sine wave signal source with a specific function,integrated use analog electronics,digital electronics,EDA technology and (PLD) application technology as the core.This experiment guide students to understand the implementation of digital electronic systems technology and PLD applications in the process of complete a electronic system.The experimental platform can accomplish the step amplitude,frequency step and phase step digital sine wave experiments.Teaching practice shows that the experiment did not only enhance the students mastery of PLD technology and the working principle of signal generator,but also give students a deeper understanding of digital system design.
