← ScienceWhich outcome results when parasitic capacitance resonates in signal filters?
A)Signal attenuation near resonant frequency✓
B)Increased signal integrity at all bands
C)Stable impedance across operating range
D)Reduced power consumption within the load
💡 Explanation
Signal attenuation happens because parasitic capacitance creates unwanted resonant circuits; increased impedance at resonance impedes signal transmission. Therefore signal weakens near resonance, rather than improving integrity across bands, because the reactive impedance is frequency-dependent.
