Homework Statement
find z transform of:
x[n] = (1 / n!) *u[n]
u[n] is the unit step
Homework Equations
z transform equationX(z) = Ʃ x[n] * z-n
summation is from -∞ to +∞
The Attempt at a Solutioncancel the u[n] by changing the bounds of the summation
now it is from 0 to +∞It's at this...
Just curious, how does one switch from the frequency version of a Fourier transform to the ω version. I know that ω = 2∏*f
but looking at the variations of the table it seems like there is more than just this difference
thanks for the reply!
it has to be true for all n to be periodic by definition i believe.
i mean, I've personally never heard of a sinusoidal period being a function of time (in this case discrete time)
And there are an infinite number of 'N's (provided it is periodic) but I am...
Homework Statement
Determine whether x[n] is periodic, if so find the fundamental period.
ps forgive my notation, I'm new to physics forums and haven't had a chance to figure out the exact notation syntax yet.x[n]=cos(π/6 * n^2)
The Attempt at a Solution
x(n) is periodic when x(n) = x(n...
