Experimental Steps
Both Butterworth and Chebyshev filters were designed and analyzed using LTSpice simulations. The following steps were carried out:
- Construct circuits in LTSpice.
- Calculate frequency cut-off.
- Perform AC Analysis to observe ripple voltage.
- Analyze roll-off rate and frequency response.
- Perform transient analysis at different frequency ranges.
- Generate Poles-Zeros plots using MATLAB.
- Compare theoretical values with simulation results.
- Discuss findings and conclusions.
