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
