说明：  AsK: 幅移键控ASK (Amplitude Shift Keying) ASK指的是振幅键控方式。这种调制方式是根据信号的不同，调节正弦波的幅度。 askdigital([1 0 1 1 0 0 1 0],2) 输入
(AsK: Amplitude Shift Keying ASK (Amplitude Shift Keying) ASK refers to the amplitude shift keying method. This modulation is based on the different signals to regulate the magnitude of sine wave. askdigital ([1 0 1 1 0 0 1 0], 2) input)
