Write a Matlab code to generate the signal y(t)=10*(cos(2*pi*f1*t)+ cos(2*pi*f2*t)+ cos(2*pi*f3*t)), where f1=500 Hz, f2=750 Hz and f3=1000 Hz. Plot the signal in time domain. Sketch the Fourier transform of the signal with appropriately generating frequency axis. Apply an appropriate filter to y(t) so that signal part with frequency f1 can be extracted. Sketch the Fourier transform of the extracted signal. Apply an appropriate filter to y(t) so that signal part with frequency f2 can be extracted. Sketch the Fourier...

Fi 60 135 60° 609/ 30 (4 m, 4m,-2m) If F1- 8.26 KN, F2 3B4 KN, and F3 12.2 KN, determine the magnitude and direction of F required for equilibrium. F1 is rotated 30 degrees in the x-y plane and 60 degrees up in the z direction. Alpha, Beta, and gamma for F2 are 135, 60 and 60 degrees, respectively. F3 passes through the origin and another point (4,4,-2).
(MATLAB Question) Assume s1 = sin(2*(pi)*f1*t), s2 = sin(2*(pi)*f2*t + 0.4) and s3 = s1 + s2, where f1 = 0.2 and f2 = 0.425. Plot s1, s2 and s3 vs t with t=0:0.1:10 on the same graph (you have to use hold on command). Label the axes and create legends for each graph.
Suppose we have two hierarchies of classes. C1 is a superclass with D1, E1, and F1 as concrete subclasses and C2 is a superclass with D2 and E2 as concrete subclasses. C1 has abstract methods f1() and g1() and C2 has abstract methods f2() and g2(). There is Bridge from C1 to C2. Use the above scenario for answering questions 1-3. Question 1 (1 point) Each object of type C1 should hold a reference to an object of type C2....
