If we choose a Chebyshev filter for the design, the normalized analog filter is exactly the same third-order Chebyshev lowpass filter obtained in Example 4.3. The normalized analog lowpass filter has a transfer function Ha(s)=0.3269(s+0.3689)(s2+0.3688s+0.8861) ...

A low-pass filter is a filter that passes low-frequency signals but attenuates (reduces the amplitude of) signals with frequencies higher than the cutoff frequency. The actual amount of attenuation for each frequency varies from filter to filter. It is sometimes called a high-cut filter , or...
