solve problem 1

General Description You are tasked to diagnose a strange random noise in a gear box. Your diagnostics equipment measuring vibrations is controlled by acall toa Matlab function [t,] = signal (time, freq); where time is for bow long measurements are taken in [5] and freq is the data acquisition frequency in [Hz]. The freq value must be a positive whole number, The output of the function are the column vectors t containing the measurement times in [s] and y containing the dimensionless measured values. It is known that the gearbox vibration signal will have meaningful data only in the 0.75Hz to 210Hz range. Problem | / Gradescope (20 points, CCOs #7 #11) State the minimum time thal measurements must be taken (the value of time) and the minimum data acquisition frequency (the value of freq) to cover the meaningful gearbox vibration signal data. Take a measurement for those values and graph the measured data y(t). Hf you are unable to determine the values of time and freq, use time = 17 sand freq = 270 Hz here and inall following problems. Required submission: Oo aintnien measurement time and minimum data acquisition frequency; O printout of well annotated graph showing y(t): 0) printowr of script used to solve this problem (can be a single script for all problems): only use functions developed in this class or this exam to solve the exam problems. If an equivalent build-in Matlab function is used for a function developed in this class, no credit will be given. The appendix lists the functions developed in this class. The use of Matlab's \\, operator, inv(), inverse), ~! for matrices, or any other method to solve linear systems, norm), methods to solve non-linear equations, eg, fsolve(), feero(), the use of polviit(), polyval(), spline(), or similar fitting or interpolation function, diff), integration functions, c.g... trapz(), integral), inti): ft. ifft) or similar Fourier transform functions: ode45(), or ode23(), or similar ode solution functions will be considered a violation of the academic integrity policy. = brute force searches are neither acceptable nor a numerical method in this class and therefore will give no credit
