Being alive in the 21st century, you've no doubt noticed that there are a whole lot of digital electronic devices around. You can't just jam a wire from your circuit board into a computer and have it transmit data, so we sometimes need a way to map a range of analog values into discrete digitized values. Digital devices also tend to react poorly to being subjected to voltages higher or lower than their desi… text/html 2025-10-16T17:41:21+00:00 Anonymous (anonymous@undisclosed.example.com) http://physlab-wiki.com/phylabs/lab_courses/phys-226-wiki-home/component_library?rev=1760650881&do=diff Diodes Small Signal 1N914 - Can change from conducting to insulating in a few ns Power 1N4004 - Rated to handle 100s of volts and 10s of amps of current (briefly) Op-Amps CA3011 - Wide-band RF amplifier CA3021 CA3022 CA3023 CA3040 - Wide-band amplifier CA3140 - BiMOS Op-amp: very high input impedancecomponent_library index text/html 2026-03-11T17:32:36+00:00 Anonymous (anonymous@undisclosed.example.com) http://physlab-wiki.com/phylabs/lab_courses/phys-226-wiki-home/electronics_vocabulary?rev=1773264756&do=diff Electronics Vocabulary Terms 3dB Frequency The 3dB frequency of a filter is defined as when the voltage gain $V_{out}/V_{in} = 1/\sqrt(2)$. There's a slight rounding difference when converting to decibels as $20\log(\sqrt{2}) = -3.012 \mathrm{dB}$, but that would get very tedious to write. Breadboard A Breadboard is, in general, a surface designed to have circuits built on it. $P = VI$$I = V/R$$P = V^2/R$$\sqrt{2}$ text/html 2025-06-24T16:07:36+00:00 Anonymous (anonymous@undisclosed.example.com) http://physlab-wiki.com/phylabs/lab_courses/phys-226-wiki-home/fpgas?rev=1750795656&do=diff Terasic DE0 Board ---------- The DE0 Development and Education board is designed in a compact size with all the essential tools for novice users to gain knowledge in areas of digital logic, computer organization and FPGAs.
