Design requirements: ( 1) can output sawtooth, triangle wave, sine wave, pulse wave. ( 2) according to the keyboard command to switch between waveforms. ( 3) can adjust the output waveform frequency. 设计要求:(1)能够输出锯齿波,三角波,正弦波,脉冲波。(2)能根据键盘命令进行波形之间的切换。(3)能对输出的波形频率进行调节。
In Software part, it uses of C# language based on. Net framework, to achieve three forms output including: normal sleep EEG, hypnotic music and the typical waveform stimulation which includes a typical sine wave, sawtooth, pulse and so on. 软件部分采用C语言基于.net框架,可实现三种形式信号输出,包括:正常人入睡脑电信号、催眠音乐和典型波形刺激,其中典型波包括正弦,锯齿波,脉冲波等。
