I forgot one more thing. It also says find the value of \alpha for which the system can be classified in the critically stable state.

Homework Statement For a control system that has G(s)H(s) = \frac{1}{s^{2}*(s+\alpha)}Homework Equations 1 + G(s)H(s) = 0 The Attempt at a Solution Exam question i messed up . I really need to know the answer.

My attempt to the solution. (a) dy/dt + sin(t)y(t) = df/dt + 2f(t) If input is f1(t) , output is y1(t). dy1/dt + sin(t)y1(t) = df1/dt + 2f1(t) -> eqn 1 If input is f2(t) , output is y2(t) dy2/dt + sin(t)y(t) = df2/dt + 2f2(t) -> eqn2 Now system would be linear if input is k1f1(t) and...

Homework Statement Two system are given as follows :- (a) \frac{dy}{dt} + sin(t)y(t) = \frac{df}{dt} + 2f(t) (b) \frac{dy}{dt} + 2y(t) = f(t)*\frac{df}{dt} Test linearity of systems. Homework Equations The Attempt at a Solution

Homework Statement The Analog-To-Digital Converter “ADC” system shown in Fig. 1 uses 1 MHZ clock generator and a ramp voltage that increases from 0V to 1.25 V in a time 125 ms. Determine the number of clock pulses counted into the register when Vi=0.9 V and when it is 0.75 V...

How did we get this formula ?

How to prove that D = eE. Use a general proof. I know how to prove it assuming a point charge.

If one has input x(t), then convolving x(t) with impulse response of the system would give the zero-state of the system. For example, we have a system described as : (D^{2} + 4D + 3)y(t) = (D+5)f(t). I computed system impulse response which is : h(t) = 2e^{-t} - e^{-3t} Now if say f(t) =...

The original diagram is drawn in pencil. The scanned copy is not so clear (poor scanner). However, i rechecked the diagram and that's how it is. I also find connecting the capacitor directly to the battery senseless too. Thank you for your reply.

Homework Statement Battery Voltage = 12 V, C = 1uF, R = 1Kohm, L = 0.2H. Find Transient Current. See Fig for more details. Homework Equations i = Cdv/dt. The Attempt at a Solution (I think the problem doesn't make sense)

The resson behind any type of forces is exchange particles. Exchange particles are particles when they are exchanged, they give attraction or repulsion.Moreover, there are four fundamental forces in nature. They are Strong nuclear forces , Electrmoagnetic forces , weak nuclear forces and gravity...
