Analog Computing
Students will learn the principles of analog computing and its historical significance, then apply these concepts using "The Analog Thing" or virtual simulations. They will analyze and compare analog and digital signals, and communicate their understanding through written and visual representations.
Overview
Students are introduced to analog computing, which solves problems by wiring electrical components rather than writing code in a programming language. The unit opens with a debate on why analog approaches may matter for energy-intensive artificial intelligence calculations. Students then wire a first "Hello World" analog program, using The Analog Thing computer or a virtual simulation, to model radioactive decay and observe the resulting waveforms on an oscilloscope. They compare analog and digital signals and show their understanding through written and visual work. The lesson is designed as a short module for AP Computer Science and AP Physics students in grades 11-12.
