Maths and Basic Concepts

I did have a plan to write some for complex numbers, calculus, trigonometry, matrix algebra and linear algebra, that sort of thing. However since I don’t teach any of this stuff, this hasn’t been a high priority. What is here is something to help teach phasors… perhaps this might be better placed in the “Basic Electronics” category, but for now at least it’s here. There’s one about queueing systems here now as well, and one on Markov chains coming shortly.

Phasors Demo

Pretty much self-evident, this one. Click and drag the circles around the Argand diagram and the waveforms in the scope-like display will change.

Phasor Arithmetic Demo

Again, pretty much self-evident. I doubt any instructions required. However, it’s often the simplest little demos like this one that have the biggest effect – at least in terms of impact per hour required to develop the demo.

Simple Queueing Demo

Simulates and demonstrats some simple queueing schemes, used to demonstrate what is going on, and illustrate the results from a Markov-type analysis of the systems. By default it’s set up to do an M/M/1/K queue, but other arrival and service time distributions are selectable. Hopefully the operation is self-evident.

Not Math Pad

Does maths – a bit. Not very well, and I can’t really imagine many uses for this, but I’m planning to use it in some videos since it’s very intuitive and interactive, and runs in a web-browser. It’s up here just for completeness really, and so I can find it when I want to use it. Double-click anywhere on the screen to get started.
