when you amplify/boost an already a weak signal recording, you
also amplify the ___________ - ANSWER-noise
the frequency rate with which numbers are stored to represent the
analog symbol being sampled is called the ________
____________, specified in Hz
-the #s represent amplitude values - ANSWER-sampling rate
the sample rate for compact discs is _________, this means that
the sounds played back from the compact disc can go up to
___________ - ANSWER-44,100 Hz, 22,050 Hz
_________ ________ sounds get lost in a recording with a low
sampling rate, and get misrepresented as _______ _________
sounds, AKA ___________ - ANSWER-high frequency, low
frequency, aliasing
,2|Page
_______ _________: filtering before digitizing which prevents
aliasing
-set filter to nyquist frequency and any frequencies above it are
deleted and cannot contaminate the recording
i.e. using a low pass filter to prevent the higher frequencies from
even reaching the digitized system so that they won't contaminate
the lower frequency recording by being represented as an alias -
ANSWER-anti-aliasing
a ______ _______ filter allows high frequencies through and
holds back the lower frequencies - ANSWER-high pass
a _______ ________ filter allows low frequencies through and
holds back the higher frequencies - ANSWER-low pass
a _______ _________ filter allows a band of frequencies in the
middle through, and holds back both higher and lower frequencies
- ANSWER-band pass
, 3|Page
a _________ ________ filter holds back a band of frequencies in
the middle and allows both higher and lower frequencies through -
ANSWER-band reject
disordered voice- disordered vocal fold movement- change in
________
disordered articulation- abnormal movement of the articulators-
change in ________ - ANSWER-source, filter
the __________ _________ phenomenon refers to the fact that
the same sound can be produced in several different physical
ways (e.g. move the articulators in slightly different ways and still
have the same end result)
-acoustics cannot reveal all details of movement - ANSWER-
motor equivalence
_________ refers to the signal level as it comes to the recorder;
needs to be a fairly good strength to compensate for the inherent
noise that accompanies recordings - ANSWER-saturation
