Suppose I want to suppress the noise at around 100Mhz on a signal line. I can do that using a EMI filter capacitor or a ferrite bead. The frequency characteristics for both show suppression of noise at around 100 Mhz:
Left fig.: EMI capacitor
Right fig.: Ferrite bead
If I want to combine these two to have more attenuation, how does putting them in series change the frequency characteristics? Can I expect higher suppression of 100 MHz noise?
Should ferrite bead follow capacitor or other way round or doesn't matter?
