用不同的元件,做一样的三角振荡波形,上面的用示波器测得是差不多的波形!LM339与LM324是很相近的元件,我一直用LM339做振荡,没用过LM324做振荡.但有于实际需要用振荡,又要用信号放大.在电路就需要同时使用这两个蕊,为了节约成本,想了下,LM324也可以做振荡,只是多一个三极管.这样就可少一个蕊了,-With different components, so as Sasser triangular shape, the above measured using oscilloscope waveform is almost! LM339 and LM324 is very close to the components, I have been doing with oscillation LM339, LM324 do not used oscillation. But the actual need to use oscillations, but also with signal amplification. in the circuit at the same time would require the use of these two core, in order to save costs and would like the next, LM324 oscillation can do only one more transistor. Such a core can be less, and
