Homework Statement Ok I know Fourier transform pair for u(t) is pi*del(w)+1/(j*w) Am I right to say the transform pair of u(t)-u(t-1) is [pi*del(w)+1/(j*w)]-[pi*del(w-1)+1/(j*(w-1)] If not what is it? thanks

A XOR gate is a inversion gate so I still run into the same problem how would you do this?

that is correct

Homework Statement I was having a casual chat with one of my professors and he presented me with a problem that after 4 hours of attempting I believe is unsolvable. the set up is pretty simple. you have 3 inputs x,y,z that go into a system, the output is ~x,~y,~z. However you are only allowed...

this look right

Here is what I got and my assumption of the circuit. Sorry in the drawing s1 is s1 and s2 is s0

I had a cpre exam last night and this was the last question. Can some one tell me the answer, I'm curious if I got it right or not. The part that tripped me up was a 2 bit "half adder". I assumed I wasn't supposed to use a full adder. So I'm not sure what to do with the carry from the first...

Homework Statement Lets say I have 4 inputs x1 x0 y1 y0 if I have a sum-of-products say: x1x0'y1y0'+x0y1'y0 can I simplify it to x0y1'y0 by pulling out x0y1'y0 giving x0y1'y0(y0'+1) knowing that 1+y0 is 1 and 1*signalz is signalz. Am I right in thinking this, I really don't want to...

I know its not right by Demorgan's law, but the cryptic answer my prof gave and the fact that the problem worked out. Leads me to believe there is something to this. I was just wondering if anyone knows.

Homework Statement I not sure if this is the right place for this, so move me if you need. Ok let's say I have the function xyz+xy'z' - can I pull a x out giving x(yz+y'z') and say that yz=a giving x(a+a') which is x(1) or x. If this is true that means a=yz so a'=(yz)'. Can you distribute...

Homework Statement can anybody help with finding the function whos expansion is this -(5/16)x^7+(21/16)x^5-(35/16)x^3+(35/16)x I looks like a function of sin(X) but I just can't nail down what it is. Homework Equations The Attempt at a Solution

lol wow I feel stupid, its measuring a 3d space formed by the cardiod and the plane of f(x,y) and g(x,y). I get it now

Homework Statement Here is the region R plotted in the xy plane by the functions X(t)=cos(t)(1-cos(t)) Y(t)=sin(t)(1-cos(t)) go with f(x,y)=3+y-x and g(x,y)=3-x calculate ∫∫_R f(x,y) dxdy and ∫∫_R g(x,y) dxdyHomework Equations The Attempt at a Solution I know I need to use the Gauss-Green...

x/(1-x) when x=1/3 gives the correct bottom but then I just need to square the bottom function to get the top so the f(x)=x/((1-x))^2 gives the expansion of 1/3+2/(3^2)+3/(3^3+4/(4^4+...+k/(3^k) Thanks bouncing ideas I got now.
