S-R Latch and a Gated S-R Latch (Experiments 3.1. Sequential Logic. Derek Molloy)

This video demonstrates two circuits: First - an S-R Latch that is created using two NOR gates. It can be set or reset using the two inputs on the left hand side and shows how a basic flip-flop works. Second - a gated S-R latch that adds an enable input to the circuit, which must be pressed before the state can be changed. This is one of the first circuits in the EE223 Introduction to Digital and Analogue electronics module at Dublin City University. The associated materials are at: ~molloyd/EE223/
