通过AD9851产生正弦波，通过STC12C5A60S2单片机控制MAX306实现幅度键控，进而实现2ASK调制信号。-Generate a sine wave through AD9851, MAX306 chip control achieved by STC12C5A60S2 amplitude shift keying, thus achieving 2ASK modulated signal.

基于单片机的2ASK调制与解调，输入信号为伪随机M序列(2ASK modulation and demodulation based on single chip microcomputer, the input signal is pseudo-random sequence)
