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,
develop an electric equivalent network (a) using the force-current analog, and (b) using the force- voltage analog, and find u(t) for F(t) = 40e-t/4 N.
Q. Mention some characteristics of transistors? · When a NPN transistor is working, there is always a constant 0.6 volt drop between the base and emitter, i.e., the base is alw
What are Difference Equations? A continuous-time system can be described by differential equations. Likewise, a discrete-time system can be explained by difference equations. T
