从的等效电路看到,这个振荡电路是一个桥形电路。R1CR2CRt和RE1分别是电桥的4个臂,放大器的输入和输出分别接在电桥的两个对角线上,所以被称为RC桥式振荡电路。RC桥式振荡电路的性能比RC相移振荡电路好。它的稳定性高、非线性失真小,频率调节方便。它的振荡频率是:当R1=R2=R、C1=C2=C时f0=12πRC。它的频率范围从1赫~1兆赫。调幅和检波电路广播和无线电通信是利用调制技术把低频声音信号加到高频信号上发射出去的。

各位好,我本身是做家装设计师的,本来收入稳定,一次的机缘巧合之下解除了电力行业,跟着一发不可收拾的爱上了电力行业,我本身是喜欢向高难度挑战的,认为这个行业非常的适合我,所以,慢慢的电力行业变成了我的主业了。说说电力行业吧,我现在是做低压电的,但是我也觉得很有挑战性,从一开始的如何认识电线,电流,电压等等一步步走过来,现在也有好几个年头了,不知不觉得做了好几年了,慢慢的从新手变成熟手,再到师傅级别,一步步的走过来,刚刚开始就是奔着薪酬去的,因为电力属于特种行业,工资比外面的普通工种都高,后来慢慢的爱上了这一行。
