Q. For the mechanical spring-mass-friction system shown in Figure, the differential equation relating the force F(t) and the velocity u(t) is given by
where M is themass,Dis the friction, and Cm is the compliance (reciprocal of stiffness) of the spring. For M = 20 kg, D = 4 kg/s, and Cm = 8 N/m,

Q. The response y(t) of a linear system to an excitation x(t) = e -2t u(t) is y(t) = (t + 2)e -t u(t). Find the transfer function.
Q. Write notes on clamping ? Clamping network shifts (clamps) a signal to a different d.c level, that is it introduces a d.c. level to an a.c signal. Hence, the clamping networ
