DTMF双向收／发集成电路MT8880专门为双音频信号的收、发而设计，它既能产生发送双音频信号，又能对双音频信号进行接收译码，还能判断各种信号音(拨号音、回铃音、忙音)。以上就是它的应用电路和程序-Two-way DTMF collection/fat MT8880 IC specifically for the dual audio signals received, the design, it could have sent dual audio signal, while the dual audio signal decoding receiver, but also to judge the sound signal (dial tone , ring back tone, busy tone). Above is its application circuit and procedures

此资料里有单片机的仿真实例。本人试了非常有用。希望此资料对大家有所帮助！-This information, there are examples of microcomputer simulation. I tried very useful. I hope that this information be helpful to everyone!

系统能够产生正弦波、方波、三角波。同时还可以作为频率计测频率。函数信号的产生由MAX038和外围电路完成，能产生1Hz―20MHz的波形。-system can produce sine, square, triangle wave. Also as frequency measurement frequency. Signals generated by the MAX038 completed and the external circuit, which can produce 1Hz- 20MHz waveforms.
