Question

Please answer using Matlab Software. Also please show the graphs in Matlab along with the Matlab Code.

Thank you!

Part 1 Review the theoretical derivations of the amplitude and phase response of an RC low pass filter at the end of the assignment; Review the Matlab example 4-1 included at the end of the assignment; it includes the Matlab directions on how to plot the amplitude response considered above. The plot in the Matlab example displays 2 decades of normalized frequency, from 0.1 to 10. For your computer experiment you are asked to plot the amplitude response of a first order low-pass RC filter for the following cases. Consider at least 3 particular sets of (R, C) values (you pick the values!). This will correspond to different filters with different cut-off frequencies. You can plot the responses individually or all on the same graph, just label them properly, and use a legend to identify each curve if they are plotted together. You may plot as in the textbook example only 2 decades of the response, or if you find it necessary you can add one more decade. Also, the example from the textbook uses the normalized frequency u, and does not show the particular cut-off frequency in each case. It would be preferred to use the formula in f (see below) Discuss the curves relative to the values selected for R and C. How do R and C influence the shape of the response? (Hint: pick the (R,C) pairs such that to get different values of fc and be able to discuss how the circuit elements affect this frequency) AiF
