The physics of sound and the process of converting analog audio waves into digital data using the Nyquist-Shannon sampling theorem.

How video frames are captured, interlaced versus progressive scanning, and broadcast standards (NTSC, PAL, SECAM).

High-performance Central Processing Units (CPUs) and Graphics Processing Units (GPUs) process heavy computing loads. Input devices like digitizers and high-resolution cameras capture analog data, while output devices like high-refresh-rate displays and spatial audio systems render it.
