我们在设计和应用电子电路时,常常会遇到一些计算问题。由于一般的电阻器、电感器、电容器等元件与其标称值之间有一定的误差,因此,在不影响电路性能的情况下,利用本文所介绍的几个设计图是符合多快好省的原则的。图1是谐振时的感抗—频率—容抗计算图。在谐振时,谐振频率fr为fr=1/2π(LC~(1/2))只要知道了fr—L—C三个量中的任二个量,就可利用一条直尺在图1中迅速地找出第三个量。具体方法很简单,将已知的两个点(即代
We often encounter some computational problems when designing and applying electronic circuits. Due to the general resistors, inductors, capacitors and other components and their nominal value of a certain error, therefore, without affecting the performance of the circuit, the use of several of the drawings presented in this article is in line with the more rapid and economical Principle Figure 1 is the resonant impedance - frequency - capacitance calculation. At resonance, the resonant frequency fr is fr = 1 / 2π (LC ~ (1/2)). As long as any two of the three fr-L-C quantities are known, Quickly find the third volume. The specific method is very simple, will know two points (ie generation
