Computing Fundamentals Tutor Memory Cells 04: D Flip-Flop

This video shows the creation of a simulated D Flip-Flop.

It is one of a series on bistable digital circuits, which have many uses, primarily because they can "remember" things, which make them useful in sequential signal generation and as digital memory. D Flip-Flop is an adaptation of the SR flip-flop with eliminates the unstable state when both inputs are high. This is a well-known circuit and the basis of digital memory.

This series in turn is part of a larger series that charts the creation of a simulated 4-Bit CPU, with clear explanations of what is happening at every step of the way. Following this Super-Series is a great way to gain a strong understanding of the hardware that underpins computers, and is a great learning experience for anyone interested in computing as a career or hobby.

Roadmap:

Understanding the basics of digital electronics is fundamental to the understanding of computer hardware, and this software allows you to explore that without the need for hardware, soldering irons and the such like.
