基于labwindows/cvi的相关程序,生成扫频的正玄波-Based on labwindows/cvi-related procedures, to generate the sine wave sweep

基本的正弦波描述，有基本的功能，代码相对比较简洁。-Basic sine wave descr iption, the basic function, the code is relatively simple.

RC震荡的基本思想是正反馈加RC选频网络.RC选频网络之所以选出正弦波主要是因为电容的充电曲线.-The basic idea is that a positive feedback RC oscillator frequency selective network plus RC RC frequency selective network is the reason why elected sine wave because the capacitor charging curve.
