Q1) Consider an LTI system with frequency response (u) given by (a) Find the impulse response h(0) for this system. [Hint: In case of polynomial over pohnomial frequency domain representation, we analyce the denominator and use partial fraction expansion to write H() in the form Then we notice that each of these fraction terms is the Fourier of an exponentiol multiplied by a unit step as per the Table J (b) What is the output y(t) from the system if...
A Pendulum with air resistance Pendula are widely used in applications including accelerometers and seismometers and are a model system to study vibrations and damping. Consider a pendulum comprising a small mass m that is connected by a thin massless rod of length l to a hinged support The hinge is frictionless but the mass experiences air resistance as it swings. The air drag force on the mass is Fdrag-kv |v, where v is the velocity of the mass and...

System Description A video camera system, similar to that shown in figure below, can automatically follow a subject. The tracking system consists of a dual-sensor and a transmitter, where one component is mounted on the camera and the other is worn by the subject. The sensors receive energy from the transmitter. An imbalance between the outputs of the two sens system to rotate the camera to balance out the difference and seek the source of energy. The angular movement of...
