Compute the resonant frequency fo for the series RLC using equation (2) and compare it to the measured value.
Considering the values used for the experiments: C = 1.0 µF, L = 20mH we can compute the resonant frequency as follows:
Compute the magnitude and phase for the series RLC circuit when the reactive component equals the resistive component.
The impedance of the series RLC circuit is defined as:
Reactive component equals the resistive component implies:
The magnitude results:
The phase is computed as follows:
I am looking to use an RLC circuit to do EMI filtering for a pulse discharge from an IC. I am wondering what people think of these values. R = 1mOhm , L = 1mH ,C = 100uF .... Will anyone say if this is good noise filtering for a 5 volt circuit? I am trying to preserve the integrity of the signal, while also cutting off high and low frequencies
The easiest way to see if the values fit your design, is to actually simulate them. LTspice offers you a pretty nice environment for this.
