    Solving for Bode Critical Frequency: Guide and Equation Explanation

    I am given a bode plot and have to label the cutoff frequency on there. G(jw)=2/(-w^2 +162jw +320) I got this equation where w is the critical frequency: 70922=81^2 + (170 -(w^2/4)) I am sure that this is wrong since I get the sqrt of a negative number for w. It would be really great...

    How Do You Determine the Critical Frequency in a Bode Plot Equation?

    Given an equation like 2/((jw)^2 +54jw +44), how would you find the critical frequency? I am getting a umaginary number and I am sure this is not true, please help!

    C Programming with Interrupts: How to Avoid Polling and Optimize Processor Usage

    Using interrupts means that polling doesn't have to be used which ties up the processor repeatedly checking. Maybe it is different polling the interrupt flag...Is there any other way of writing the program to NOT include the polling there?

    C Programming with Interrupts: How to Avoid Polling and Optimize Processor Usage

    The code is supposed to be run on a pic18f8722. When one of the pushbuttons is pressed, then an interrupts should be generated. I am mainly worried about the polling. I shouldn't be doing this I don't think. I wrote this a few months ago and now I am looking I am confused at what I was doing...

    Two's compliment of SIGNED binary

    Thanks for all of your help! You are right. He just looked at a different question when he was writing the problem I think.

    Two's compliment of SIGNED binary

    Hey! Thank you so much! My lecturer gave us some questions and in one of the answers he came up with something completely different and it was the only example so I have been struggling over it for at least half an hour! Everyone is human I guess and makes mistakes...but are you sure that this...

    C Programming with Interrupts: How to Avoid Polling and Optimize Processor Usage

    Hi everyone~ I think that I have used polling here where I shouldn't have done. Does anyone have any ideas? #include "p18f8722.h" #include "timers.h" void configure_PB2_interrupt (void); void enable_global_interrupts(void); unsigned char PB2_pressed (void); void isr...

    When to use ADCON1 in c programming on the pic18f8722

    Under what circumstances would you use ADCON1=0x0F? All I know at the moment is for using the pushbuttons and using the switches and then I saw a piece of code using the pushbuttons without this line in it and I was wondering whether I was wrong all of this time. I have tried googling and...

    Two's compliment of SIGNED binary

    The twos compliment for regular binary numbers- you just replace all 1's by 0's and 0's by 1's and then +1. So how would you go about finding out for signed...I have got as far as changing the first digit then that's it! Does anyone know what to do?

    Thermodynamics: P,V,T graphs and other misc. questions.

    If you wrote a book with these things in you could probably sell quite a few copies because I think a lot of people have problems getting clear on some parts, like, containing the graphs for each process. I'm just saying cause there arent many clear concise ones out there, and I've seen quite a...

    Thermodynamics: P,V,T graphs and other misc. questions.

    Oh thank you! If you actually enjoy being asked thermo questions then I've got a few more for you! :) I've been trying to do question 2 above sticking to your tips and I couldn't tell what type of process it was so I just put "Process:not isobaric, isometric, isentropic or reversible. Ideal gas...

    Thermodynamics: P,V,T graphs and other misc. questions.

    Hey! You seem to kn ow what youre talking about here and I am stuck on a similar question, so is it ok if i ask you something? Basically I found your tips on things that you need to include when solving the question really helpful, and I was wondering, should you sketch graphs of specific volume...
