Final answer:
A 3rd order high pass passive filter attenuates low-frequency signals while allowing high-frequency signals to pass through.
Explanation:
A 3rd order high pass passive filter attenuates low-frequency signals while allowing high-frequency signals to pass through. In the amplitude frequency response, there will be a gradual increase in attenuation with increasing frequency. The phase frequency response will show a phase shift of 180 degrees at the cutoff frequency.
