介绍说明
1 用存储器或算法得到信源。
2 用DA转换器输出一函数信号(正弦、方波、三角、锯齿等,频率1000Hz),可以用示波器进行波形观察。
3 用数码管或LCD显示输出参数。
4 用功能键切换各信号的输出。
发挥部分:
1通过键盘,可修改波的频率。每按一次键,频率值进给或后退1倍,频率范围不限。
2通过按键可以修改输出波形的幅度。
3按键时,蜂鸣器发出提示音,表示按键有效。
4数码管或LCD显示的内容可以用频率值和周期值切换表示。(1 use memory or algorithm to get the source.
2 use DA converter to output a function signal (sine, Fang Bo, trigonometry, sawtooth, etc. frequency 1000Hz).
3 use the digital tube or LCD to display the output parameters.
4 switch the output of each signal with the function key.
Play a part:
1 through the keyboard, the frequency of the wave can be modified. Each time the button is pressed, the frequency value is fed or retreated 1 times, and the frequency range is not limited.
2 the amplitude of the output waveform can be modified by the key.
When the 3 button is pressed, the buzzer gives out the prompting sound, which means the key is effective.
4 the contents of digital tube or LCD display can be switched by frequency value and cycle value.)
