摘要
对Delta脉冲调制器的性能进行了理论分析和计算.结果表明,Delta脉冲调制方法与常用的最佳取样原则相符合.文中给出了一种Delta脉冲调制电路,介绍了其恒幅变频正弦波的一种独特的产生方法.
The performance of a delta pulse modulator was analyzed coretically.The modulation agreed with the usual principle of optimum sampling. A practical circuit of Delta pulse was given. A particular method for generating constant-voltage and variable-frequency sinusoidal wave was recommended.
