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
Specifically I am trying to filter the AD7793 for a thermocouple temperature sensing application.
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.
