After checking the individual behavior of the components, the schematic using microstrip lines is made for the whole 7th order Butterworth filter and then also the layout of the schematic is shown below. This step involves replacing the high-frequency components with transmission lines and ensuring that the layout accurately models the ideal components. The microstrip lines are designed to accurately model the inductors and capacitors in the high-frequency range, ensuring that the filter operates as intended

The 6th order butterworth filter having roll of  Answer dB/decade

The 4th order butterworth filter having roll of  Answer dB/decade

Design a Butterworth highpass filter to meet the specifications :The Gp > -1 dB, < -20 dB cop=20 rad/sec and Ws = 10 rad/se

A Digital filter with a 3dB bandwidth of 0.5π is to be designed from 1st orderanalog butterworth filter using BLT and obtain H(z

, whatcutoff frequency should you choose and why? Determine the order of the filter (as discussed inclass), if the stopband ripple factor . Use the butter command to create the filter
