logic circuit

Hello all, I’m helping my daughter with a design project and part of it needs a simple led control circuit. Using a single push button and 4 leds, I need an ic circuit that would light led 1 with th e first button push, led 1 &2 with the second, led 1,2,&3 with the third button push, leds...

Hi, I need help with writing a state table of 7 segment with 4-bit input A,B, C "Present state", and x "Input".

Here is my Hardware Interlock Circuit for Gate Signals which prevents both PWM Signals to be at same state at any given time. Here I want to reduce this two AND Gate IC's into a Single AND Gate IC. Or Is there any other way to implement the Hardware Interlock for Gate Signals ? Is there any...

Hello Everyone, I am designing a circuit that operates on pressure sensors to turn lights from red to green, green to yellow, and yellow back to red. I am implementing 2 of the 4 sides of an intersection due to redundancies. How would I design a circuit with 2 inputs and 2 outputs? My plan is...

Hi, I am only on my 5th week trying out TinkerCAD for our Logic Circuits course. We are tasked to create a 7-Segment Display Using Logic Gates only. I did all the boolean expressions needed for each segment using K-MAP, and identified the boolean expression needed to create my circuit. I am...

Hi, How can I implement a 2-bit decoder using a 4 to 1 multiplexer ?

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...

Hello, This is my first post here. I'm trying to learn electronics on my own via different sites At the moment, I'm trying to understand how a NOT inverter works. I perfectly understood what it was used for, but something escapes me on this diagram...

Hello. This is JK flip-flop. I have to convert it into D flip-flop, that it does the same what JK does. Then I have to draw a logic circuit of D flip-flop. I don't know what to do, can you help me?

I want to construct a circuit that calculates the absolute value of a signed 4-bit number in two's complement! So the logic here : assuming we have B = b3 b2 b1 b0 . If b3 is '1' then then b is already in 2s complemnt and should be assigned directly to the output else if b3 is equal to '0' then...

Hi, I am trying to see if this interface will work. I am worried about the Vol to Vih relationship as there is no margin. The vendor of the driver thinks it will be ok. Here are the parameters: Driver: Voh=2.3V (min), Vol=0.8V(max) Receiver: Vih=2.0V(min), Vil=0.8V(max) So as you can see...

Hello everyone, i have these two school projects and i tried my best to simulate them in Proteus, and so far no desired output :( Can you pls help me fix the issues they might have? First project is about making a two-digit binary adder and subtractor with seven segment display by using full...
