说明：  可以仿真所有常见的数字通信信号，如2ASK、4ASK、8ASK、2FSK、4SFK、8FSK、16FSK、BPSK、QPSK、8PSK、16PSK、16QAM、32QAM、64QAM、128QAM、V.29等等。信号的各种参数可以自己随意设置，提供参数输入接口。需下载ni调制工具包。
(Can simulate all common digital communication signals, such as 2ASK, 4ASK, 8ASK, 2FSK, 4SFK, 8FSK, 16FSK, BPSK, QPSK, 8PSK, 16PSK, 16QAM, 32QAM, 64QAM, 128QAM, V.29 and the like. Various parameters of signal can be freely set their own to provide the parameters input. Need to download ni modulation toolkit.)
