silence during digital audio playback.
DYNAMIC HEADROOM
The ability of a component to correctly duplicate high
speed, high level transient signals in excess of those
normally encountered in audio playback. If a comp, onent
does not have sufficient Dynamic Headroom, it will
either fall short of the actual intensity and accuracy of the
transient, or possibly distort it.
FIBRE OPTIC
An interconnecting link through which digital data is
transmitted via a beam of light.
INSTRUCTION CYCLE
A period of time in which a processor completes a single
or series of operations.

crease the time domain resolution of the playback wave-
form.

UANTIZATION
e process by which analog music is converted into
digital data.
RFI
Radio-frequency interference. This equipment generates,
uses, and can radiate radio frequency en.ergy which can
cause interference to radio communications.
SAMPLES
A digital sample is a quantized coordinate representing a
specific amphtude at a specific time. Thousands of
samples per second are quantized during recording to
digitally represent the original music.
SAMPLING RATE
The frequency at which analog data~:~is sampled in the
recording process (ex. a Sa~m,l~],ing Rate of ~4.1KHz
which is used in recording CD s represents 44,100 quan-
tized samples per second).
