ECE 110/120 Honors Lab Section : Boolean Calculator

Statement of Purpose 

Description: 

Our project involves creating a digital circuit that allows users to convert unsimplified boolean expressions into their simplest forms. Ideally we want to be able to have the calculator take up to 4 variable expressions and convert between POS and SOP forms. 

Background Research 

Boolean calculators have been designed before, but most only take 3 variable inputs and return SOP forms only. Ours will be able to take up to 4 input variables as well as return expressions in both SOP and POS forms. This project would involve both a digital and software components which makes the work more appealing to us. Also we frequently encounter boolean simplification in ECE classes so having a calculator would make the process quicker.

System Overview 

We will have three input feeds into the microcontroller(switch for 3|4 variables, switch for POS|SOP, and buttons representing inputs for the unsimplified logic expression). The microcontroller will then convert the inputs into a simplified expression and display the result either through LEDs or a small digital display 

Parts 

Provide a list of parts that you may need for your project. You should include details such as the quantity, model number, purpose, vendor, and price (excluding taxes and shipping) for each part. This list may change as you work on your project. 

Possible Challenges 

Please list some of the challenges that your group foresee in working on your project. 

• Converting between POS and SOP forms could be an issue if we use LEDs to display the output, but a display screen could solve this
