A capacitor with a Q of 200 is combined with a coil with a Q of 80 and a 20 k ohm resistor to produce a parallel tuned circuit resonant at 60 * 10^6 rps. Letting C = 25 pF, find the bandwith of the resultant circuit.
Can anyone help me with this problem?
Re: solving
So you need to make a matrix. Say it is four by four. Then here is the code:
each semicolon separates a column of the matrix.
A = [1 2 3 4; 1 2 3 4; 1 2 3 4; 0 0 0 0];
rref(A);
display(A)

They represent the rows i think, I mean. Sorry.
why do we need complex number?
I've been told that it makes calculations easier. Complex numbers are something I think you just get you use to as a tool. It's kinda funny that such weird numbers would serve such a practical use.
When you hit the ball, you give the ball kinetic energy and the ball loses this kinetic energy due to friction with the air and surface it travels upon in the form of heat. If the surface is uneven, there is a constant dwindling and increasing, to and fro, of kinetic energy being exchanged for...
Re: solving
I guess you are looking for the nontrivial solution. I think you should solve it So, I am sure that Matlab has a function to put a matrix in row reduced echelon form. Create a matrix with A columns and the last column being all zeros. I know this is of limited help, but your...
THe Laplace transform of e^(-at) is 1/s+a so 1 = e(-0t), so its transform is 1/s.
Added after 2 minutes:
so for 0, we got e^(-infinity*t), so for 0 it is 0.
