A circuit that filters out a certain frequency is shown in the figure. In this filter, the ratio of the magnitudes of the voltages is given by:

where ω is the frequency of the input signal.
Write a user-defined MATLAB function that calculates the magnitude ratio. For the function name and arguments, use RV = filt-freq (R, c, L, w). The input arguments are R the size of the resistor in n (ohms); C, the size of the capacitor in F (farads); L, the inductance of the coil in H (henrys); and w, the frequency of the input signal in rad/s. Write the function such that w can be a vector.
Write a program in a script file that uses the filtfreq function to generate a plot with two graphs of RV as a function of ω for 10
