Section 15.3(k)
A digital device is a device or system that generates and uses digital timing signals
operating at greater than 9,000 cycles per second (9 kHz). Many types of electronic
equipment and consumer products are digital devices because they contain circuitry
using such digital timing signals. Examples of digital devices include computers,
calculators, digital watches and clocks, automotive electronic systems, and most
telephones, microwave ovens, video cassette recorders, and security alarm systems.
Peripherals to a Digital Device
Any device that feeds data into or receives data from a digital device is a peripheral of
the digital device. Peripherals include external devices that connect to a digital device
by wire or cable, and circuit boards within the digital device that connect it to external
peripherals. Also included are circuit boards that increase the operating or processing
speed of a digital device. Examples of peripherals are computer printers, monitors,
keyboards, printer cards, video cards, local area network cards, modems, and
enhancement or accelerator boards.
Section 15.3(r)
Peripherals to a digital device are subject to FCC technical standards because they can
generate their own radio noise or allow the escape of radio noise generated by the
digital devices to which they are connected. Peripherals to a personal computer must
be authorized by the FCC.
