Would you please not mind to show me please. I have tried this so far. please help after this. thanks

solution so far heres what I got so far.. please help after this point.. thanks

I tried And I am not going anywhere. please help

FOR TIME INVARIANT SYSTEM [ tex ] x_1(t)------>y_1(t) [ \tex ] [ tex ] x_2(t)= x_1(t-T) [\tex] ---keep this equation same [tex] x_2(t)------>y_2(t) [\tex] [tex] y_2(t)=y_1(t-T) [\tex] If all these conditions are true for that function then YES its TIME INVARIANT else its TIME VARYING...

Thank you very much for your info SGT, would you please help little bit more.

Matlab is definitely needed specially when you start Power Engineering and Signals and then on you will always need, you are absolutely right neurocomp2003. thanks for pointing that out.

AS you know Angel the rule here by the mentors are that we have to show that we tried doing it. So please show what is your approach and after that by the rule of this forum I can help you.

The DTFT of a system can be calculated from the transfer function using freqz. Define the numerator and the denominator of the transfer function in num and den. The command [H,Omega] = freqz(num,den,n,'whole'); computes the DTFT for n points equally spaced around the unit circle at the...

As Berkeman said that C and C++ will be really helpful don't bother doing Visual C if you are coming into Electrical. Also try to do Java as most of the universities teach an introductory course. IF you can try to learn VHDL and VLSI which will be really helpful because you need them for sure...

Hey first I tried taking the KVL around the loop something like -x(t) + v_c(t) + v_L (t) + v_R (t) = 0 ----(1) replaced v_L(t) with first order Ldi_L(t)/dt and make an equation for v_C(t) and then as its in series I tried to write a function for i_L(t) = \frac {v_R (t)} R ------(2)...

Generally in impulse response we replaceY[n] with h[n] and x[n] with delta[n] and put different values for n and find the values for the values for h[n]. first we re arrange the equation for h[n] and then find it. but after finding those values what should I do ? I am stuck right there.please help.

Hey I already figured out the second one. None of the answers are right. But and I told my teacher about it and he agreed with me. I am confortable doing impulse response but not this one. Generally in impulse response we replaceY[n] with h[n] and x[n] with delta[n] and put the n values as...

Yeah that's right. is multiple choice. And I have to choose the correct option.would you help me please now. Thanks a bunch.

HELP!unit-pulse response for the discrete time system problem Please help me solve these problems. Thank you so much for all your help. Compute the unit-pulse response for the discrete time system 1) y[n + 2] + 1/2 y[n+1]+1/4y[n] = x[n+1]-x[n] (for n = 0, 1, 2) For number 1) the options...

Hi I am looking for the solution manual for Fundamentals of Signals and Systems Using the Web and MATLAB (2nd Edition) by Ed Kamen, Bonnie Heck I need most of the solutions at least. If you could help it would be greatly appreciated. I will do anything to get the solutions. Please HELP.
