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

此程序实现无线信标定位，GPS产生的信号经过（7，4）汉明码编码后发送，接收端解码得到发送端坐标。程序分为发射和接收2部分，在Keil C下编译实现。-This procedure positioning wireless beacons, GPS signal generated by (7,4) hamming code is encoded to send, receive decoding client coordinates to be the sending end. Transmitting and receiving procedures are divided into 2 parts of the Keil C compiler under implementation.
