Design a discrete lowpass filter of length 15 and cutoff frequency π/3 using the Hanning window using the hanning formula. You must simulate the response in the discrete-time domain and the frequency
domain after obtaining the practical filter. In this question, you are expected to demonstrate your comprehensive capability of designing
RF filter systems. Use MATLAB to simulate the filter response.

A bandpass filter passes signals with frequencies that are within a certain range.In this filter the ratio of the magnitudes of the voltages is given by:
RV=V0/Vi=wRC/sqrt(1-w^2LC)^2+(wRC)^2 where w is the frequency of the input signal.Given R=1000ohm,L=11mH and C=8µF,determine the frequency range that corresponds to RV>=0.87.
Using MATLAB:
a) First plot the graph
b)Use matlab to construct a script for the Bisection method and Newton's method to find one of the possible roots.
