Digital Logic is a defunct Computer Science course in the CTY program. Its course code is DIGI.
This course covered the principles and practices of digital electronic design, from simple combinational logic to vast sequential systems. Students would use the skills they learned to complete projects such as rudimentary computers, or electronically controlled model vehicles.
DIGI was taught at a number of sites, including Lancaster and Baltimore, but today, DIGI is best known as the genesis of Digiclan. This well-known group, most active in the mid- to late-'90s, began with the students of DIGI.LAN.94.2, and grew to include their "fifty-plus closest friends."
DIGI itself was phased out in 2000 or 2001, and now Electrical Engineering fills a similar niche. However, EENG is more concerned with analog electronics than digital devices.
