    Sketching Frequency domain repsonses

    Ok so I figured this out straight away after posting. I meant to say that I found two zeros at -1. I then realized that I need to calculate for points around the unit circle, starting from 1 on the real axis and moving anti clockwise around the unit circle. Thanks for anyone that took time to...

    Sketching Frequency domain repsonses

    Homework Statement Sketch the z-plane pole zero diagram for: G(z) = \frac{z^{2} + z + 1}{z^{3}} Also sketch the time and frequency domain repsonses, the latter in amplitude and phase. Homework Equations G(z) = \frac{Y(z)}{X(z)} Zeros when Y(z) = 0; Poles when X(z) = 0 For...

    Should the state table include the clock and reset button as possible inputs?

    Ahh very true, hmm how could I get around that then. I know how I could do it in the VHDL code if ((clock = '1' and clock'event) and (SFW = '1' and SFW'event)) then state <= stateB; end if; Or something along those lines at least, but I'm unsure how I'd represent that in a state table...

    Should the state table include the clock and reset button as possible inputs?

    Hmm ok, it was just the part in the question about holding down the buttons for more than one clock cycle that threw me. I guess that part may only be relevant when it comes to writing the VHDL. I'm going to assume that the reset button sets everything to zero, and therefore the stop state...

    Should the state table include the clock and reset button as possible inputs?

    Homework Statement Homework Equations There aren't really any relevant equations. The Attempt at a Solution Ok so I just want to see if my idea for the state diagram seems ok, I'm going to give it in table form here but its the same info. F | Bk | A | B | C | D...

    Fixing VHDL Syntax Error: Creating Up/Down Counter

    It did indeed, I forgot that youe need to use " when dealing with 0000 instead of just 0 etc. Thank you! There's also a ton of other mistakes in there, but I cleared them up too.

    C Programming: Adding 16bit and 32bit Integers with Local and Global Variables

    Homework Statement Write a C program to use a function to add two 16bit and two 32bit integers together and return a long integer result. Call the function twice with different parameters and print the results. Declare your input variables to one of the function calls as local variables (on...

    Implementing Boolean Function F with NOR Gates

    The d means does not matter. So that values of 8, 10, 14 and 15 can be either 1 or 0, whichever gives the neatest solution. I'm unsure about the second part, sorry.

    Factorising Polynomial for Control Engineering Problem

    Yea sorry that was a typo for the first roots. shortly after writing this i realized the roots would be part of the factors and worked it out. thanks very much!

    Factorising Polynomial for Control Engineering Problem

    Homework Statement As part of a control engineering problem, I need to factorise this polynomial. s^3 + 16s^2 + 85s + 250 (EDIT: the images failed so had to write it in this form) Homework Equations I know that the roots are -10, -3+4j and -3-3j. The Attempt at a Solution...

    Discrete probability distribution

    ahhh silly little mistake again. twenty, ok getting there slowly. 1 = 20*20k + (20*21/2)k = 610k k=1/610 hows that look?

    Discrete probability distribution

    So can anyone help on how to get the expected value of R? I think you multiply the two functions by r and then work out the sum over the ranges. Not entirely sure. Oh and does anybody agree with my value of 1/230 for k??EDIT: sorry didn't see your post tedjn. Should it be 20*19k instead??

    Discrete probability distribution

    I'm pretty sure that should be 19*40 and the 20k should be taken into account too. But as tim said, I've made it too complicated.

    Finding divF and curl F for F = r/r

    ah actually never mind, I've worked it out. I had left out part of the product rule in my differentiation. I would post the full worked solution but its quite long and the forums seem to be running slow for me today.
