Characteristics of a filter
A filter has the following characteristics: Attenuation = 3.0 dB from 0 Hz to 2 kHz.
From 2 kHz to 20 kHz attenuation increases from 3 dB to 23 dB in a straight line when plotted on axes of power in decibels (vertical axis) against log frequency ( horizontal axis).

a. Is this a low pass, high pass, band pass or band stop filter?

b. What is the attenuation per decade between 2 kHz and 20 kHz?

c. What is the attenuation at 4 kHz?

d. Is this an ideal filter or does it behave like a real filter?
