The effect of zero insertion is illustrated in Figure 7.5, where the magnitude function ∣H0(ejω)∣ of an ideal highpass filter is shown together with the function ∣H(ejω)∣ resulting from setting D = 5. The D-fold repetition of the filter transfer function attenuates not only the ...
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) To illustrate the effect of ...

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...
