Questions tagged [circuit]

In a programming context, a circuit usually refers to a combination of logical operators to achieve a desired response. Use this tag to ask about basic logical implementations and loops you can't get your head around.

In a programming context, a circuit usually refers to a combination of logical operators to achieve a desired response. This could be implemented in hardware (see: electronic/electrical engineering) but in software the key issue is the logic.

Use this tag to ask about basic logical implementations and loops you can't get your head around.

Logical operators include AND, OR, NOT, NAND and NOR gates, and judicious combinations of these can be used to construct just about any possible structures.

ADC Analog to digital conversion

Can someone look at my code? I'm trying to get 8 LEDs to rotate as I rotate the potentiometer, but four LEDs stay on the whole time not rotating at all. #include /******************************************************** * xx/xx/xx - Put…

How is Boolean Algebra efficient in practise?

Thanks for taking the time, just as a note, l understand the basics of Boolean Algebra. Although l understand how Boolean Algebra is a useful optimization technique in very small circuits, surely it would take far too long in a realistically-sized…

Does one need to have Xyce installed in Windows 10 to use PySpice? Or does PySpice already run with a "Xyce engine"?

I am very unfamiliar with these low level setup instructions for open source circuit simulators. Basically, I want to be able to simulate a not too terribly complex circuit in Xyce. I am running Windows 10 and the instructions to download Windows 10…

What are the difference in delay times of the basic AND, OR, NOT, NAND, NOR, XOR, XNOR gates?

1-1 What are the difference in delay times of the basic logic gates? I found that NAND and NOR gates are preferred in digital circuit design for shorter delay time and that AND and OR gates might even be implemented with NOT and NAND/NOR gates.…

DP to find number of ways a binary boolean expression tree can evaluate to true

We have a circuit that is in a shape of a tree. The inputs are the leaf nodes, at the very bottom, and leaf nodes can either be joined by an AND gate or attached to a NOT gate. There is some root node that outputs a final value. I've been trying to…

How to print 'Hello world in python' through pressing a button connected to the terminal on a piface digital 2

I have recently purchased a 'Piface Digital 2' and have been able to create programs to light up the built in LED'S with the built in buttons (as by watching the tutorials). However now I have been trying to attach a external button via the…

How to run ngspice from command line & suppress output to terminal?

I'm learning ngspice and would like to suppress the standard output on my terminal. I didn't see a corresponding option in the user manual and am wondering if I simply overlooked it.

Create 1-bit Comparator with mux

I want to make a 1-bit comparator with 2x1 mux or 4x1. I have made this 2x1. I am stuck in this situation. 1 bit comparator with 3 2x1 mux: 2x1 mux: I have to use only the 2x1 mux or 4x1, NOT gates as well as stable volt power (0 or 1). What do I…

comparing two 3-bit numbers with a 2-bit output

I have two 3-bit numbers A2A1A0 and B2B1B0 and I have to compare them and generate a 2-bit output based on if A > B, A < B , and A = B. The only circuit I can use to implement this is a multiplexer. I've made a truth table; however, i'm not sure how…

circuits using karnaugh's map technique

A combinational circuit is to be designed that counts the number of occurrences of 1 bits in a 4 bit input. However, an input 1111 is an invalid input for the circuit and output in such case will be 00. One valid input for such circuit may be 1110…
