1. ### Fourier Transform using Transform Pair and Properties

Homework Statement Finding the Fourier Transform using Transform Pair and Properties x(t) = 2[u(t+1)- t^{3}e^{6t}u(t)] Homework Equations The Attempt at a Solution For the first problem, I got u(t) \leftrightarrow ∏δ(ω)+\frac{1}{jω} F(at-t_{0}) \leftrightarrow...
2. ### Antenna gain and tv Resistance requirements

Homework Statement A satellite link has a transmitted power output of 0.5W. This power is increased in the direction of transmission by the transmitter antenna, which has a 20dB gain. The RF signal is attenuated by a path loss of 200 dB. The total noise level at the receiver input is estimated...
3. ### Statistical Analysis for our project

Is testing the accuracy of the time to the nearest minute necessary? I find it unnecessary (I'm considering its removal from the testing) since we'll be using DS1307 which ticks approximately one second (compared to the analog one), and it is also, I believe, the one that is being used on almost...
4. ### Statistical Analysis for our project

I actually have no idea on how would we conduct our statistical analysis for our design project. We will be creating a digital alarm clock with an improvised sensor and we will also be conducting series of tests for it. Now our teacher is looking for the statistical analysis. Our testings are...
5. ### Open Circuit Problem with Logic Gates

I would like to bring this up again. I've tried placing a 47K resistor in series with the input gates and let the input floating. Unfortunately, it does not give a low logic input. I really need to set the input to 0 because my circuit will always have a floating input. The insulator between...
6. ### Open Circuit Problem with Logic Gates

Yes, I just left the input floating. I did research about this pull-down resistor. And based on this, its just a normal resistor with values raging from 10K-47K, am I right? I also created a schematic of how I imagine the circuit would be. I have no simulators installed in this computer so I...
7. ### Open Circuit Problem with Logic Gates

I wonder how can I make the logic gate read 0V when it is open? For instance, the AND logic gate. If one of its input pin has 5V supply, and the other don't have, the output signal given to me is 5V. How can I make it 0V? Well, theoretically, it should be 0V, but in reality, it appears that...
8. ### Different LED displays (Assembly)

I guess we're not having the same thought, or I am completely lost to what you are saying. I am sorry. >.< Well, yes, normally a PC does not have a LED display. The LED display I am referring is the string values I have declared in the .data, where 1 is an indicator that the LED is on and 0...
9. ### Different LED displays (Assembly)

I tried calling the displaymenu function (from my new code) inside the BLINKING loop but it stops displaying the menu, unless I choose another display. Has it something to do with the int 01h function? .model small .stack 64 .data options1 db "[A] Blinking",10,13 db "[B] Alternating",10,13 db...
10. ### Different LED displays (Assembly)

OK, OK, sorry I misinterpreted what you've said. The only display is a black screen with my desired input and nothing at all. (Or that's not what you're pointing out?) Anyway, I was able to resolve the problem already (The relative jump problem). Next thing to do is to display the message...
11. ### Different LED displays (Assembly)

Our professor said that its fine if the program can be executed only once, as long as all the routines are working. By the way, the problem remains the same.
12. ### Different LED displays (Assembly)

Homework Statement Create a Menu to run a program for LED sequences using procedure calls or macros as follows: [1] Blinking LED [2] Two at a time [3] Alternate [4] Rotate Right [5] Rotate Left . The program will display „1‟ for LED “ON” and „0‟ for LED “OFF”. Use delay, message output and...
13. ### Turbo Assembler Problem

I am trying to do one character input at a time. So if I succeeded with one character, the next characters will be easier. I do understand what I am trying to do, but, to be honest, I really do not have anything except for this code we did last Monday night. I really do not understand...
14. ### Turbo Assembler Problem

Sorry for the late reply. I wasn't able to go online a while ago because I need to go to school as soon as possible or else I will be late. And sorry, I forgot to put it in the code blocks since I'm feel so tired when I posted that. Anyway, I tried to understand what you are saying...
15. ### Turbo Assembler Problem

Homework Statement We were required to use our surnames as a password to our assembly program. If the user inputs incorrect character or string, an "incorrect password" message will appear. Otherwise, it will display "correct password." The problem is I do not know how to ask several inputs. I...
