f是在 SI 系统中以赫兹 (Hz) 为单位测量的谐振频率:1 Hz = 1 sec-1. LC电路用于产生特定频率的信号。它们还用于从更复杂的信号中挑选出特定频率的信号。这种电路称为带通滤波器。LC电路是许多电子设备(尤其是无线电设备)的关键元件。它们用于各种电路,如振荡器、滤波器、调谐器和混频器。
Resonance is a phenomenon in which an external force or a vibrating system forces another system around it to vibrate with greater amplitude at a specified frequency of operation.
Sierra Circuits' RLC Resonant Frequency and Impedance Calculator computes resonant frequency and impedance of series/parallel RLC circuits.
Preview: Resonant Frequency of a Flat Plate / Electronic Circuit Card Calculator Natural frequency Vibration equation derived with the use of a trigonometric expression (Equation a), fn= Π / 2 ( D/ρ )1/2( 1/a2+ 1/b2) Natural frequency equation shown above is exact using the Rayleigh me...
BW = fc/Q Where fc= resonant frequency Q = quality factor A high Q resonant circuit has a narrow bandwidth as compared to a low Q Bandwidth is measured between the 0.707 current amplitude points. The 0.707 current points correspond to the half power points since P = I2R, (0.707)2=...
Resonance, as we have seen before, can cause strange things to happen. Let’s plot aSPICEanalysis and see what happens over a wide frequency range: lc lowpass filter v1 1 0 ac 1 sin l1 1 2 100m c1 2 0 1u l2 2 3 100m
LC电路,也称为谐振电路,谐振电路或调谐电路,是由连接在一起的电感器(L)和电容器(C)组成的电路。 如果电流由于外部影响而开始在LC电路中流动,则会发生电容器和电感器交替能量积累的影响。电容器根据其两端的电压将能量存储在其极板之间的电场 (E) 中,而电感器根据通过它的电流将能量存储在其磁场 (B) 中。
