Today, we are going to carry out a simple experiment using logic ICs to apply De Morgan First and Second Laws. They state that: – the negation of a disjunction is the conjunction of the negations – the negation of a conjunction is the disjunction of the negations Wikipedia Let’s keep the theory in the … Continue reading Applying De Morgan’s First and Second Laws using digital TTL ICs

Last time we started to look into digital electronics. One handy building block for our experiments is the facility to provide input values to our circuits. An easy way to do is by using DIP switches but I find it always difficult to toggle the positions of the switches. Also, sometimes we want to provide … Continue reading BCD Switch

One important beginner’s tool for his electronics lab is the cheat sheet. This is a double sided A4 page with the main references for your daily electronics need. Here is the one that Clounce prepared and uses during his experiments. Download your copy from my github repository. As described in the readme.md file in my … Continue reading Electronics Cheat Sheet

In our first blog about Digital Electronics, we are going to look how to set up our lab to do a basic experiment using NOT gate. This is by no means an extensive tutorial, but a practical session that can help you get started in your new hobby. The Power Source Let us dive into … Continue reading Introduction to Digital Electronics
