1. ### Checking Truth table and K-Maps for a two-way traffic light

Hi everyone, I've been assigned to work on a two-way traffic light system, for cars and pedestrians. I have made a state and truth table, along with some K-Maps I've attempted but are most probably wrong, which are available in the attached file. Based on that, I'm stuck on how to do the K-Maps...
2. ### Down counter shown on a 7 segment display using ram or rom in logisim

I need to have a 2-digit down counter based on read-only memory RAM or ROM and to show the count on a 7-segment display, all done in Logisim or in another program. Can someone help me thanks
3. ### Logisim - need help on 7 segments display of a logisim project I'm working on

I'm trying to make a high striker game in Logisim, basically, when I push on/off button, a random number from 00,01,01 ~ 09,10 will show using 7 segments display, and there will be LED showing the point. Right now I'm done with LED but I'm stuck at the 7 segments display part. I don't know how...
4. ### Need help on a logic circuit - logisim (or any simulator)

Hello everyone, I'm new here. So I've got this assignment that asks me to use JK flip-flops in order to create a circuit that obeys the following truth-table: The thing is, I have no idea on how to get these results at all. From what I understand, first two lines imply that PRE and CLR are both...
5. ### T implementation of a Shift left and shift right register in Logisim

Hi! I'm not really much familiar with Logisim simulations. We were asked to do a T implementation of a Shift left and shift right register. I know how to do the 4 bit shift left and shift right register (there are samples already online) but not the "T implementation" part. Do you have any idea...
6. ### Increase clock frequency

Hi, I’m working on a logisim project for university. I need to increase the clock frequency to 16 Hz, but the frequency must be set in the options to 1 Hz. How can I increase the frequency using only a circuit? Thanks for the help.
7. ### Logisim - clock

Hi, I’m working on a logisim project for university. I need to increase the clock frequency to 8/16 Hz, but the frequency must be set in the options to 1 Hz. How can I increase the frequency using only a circuit? Thanks for the help.
8. ### Check whether a BCD number is a palindrome or not

So i'm having trouble on a Digital Design assignment. I'm supposed to create a circuit in logisim that checks whether a BCD number is a palindrome or not. This is easy enough when the length of the number is given but apparently I'm supposed to do this without knowing the length of the number...
