由于输出的是方波，比较难听:-) 只能说是非常难听:-)为什么呢？只因为输出的是方波,包含了大量的奇次谐波。 你可以用双龙的"虚拟仪器"分别产生正弦波、三角波和方波听一下，正弦波感 觉就比较纯正，而方波则要多难听有多难听！-As the output is a square wave, more bluntly :-) can only say that it is very nasty :-) Why? Simply because the output is square wave, including a large number of odd harmonics. You can use Shuanglong
