If given a signal frequency of 12,000 Hz, what would the sampling rate be?
a.) 6,000 Hz
b.) 24,000 Hz
c.) 10,000 Hz
d.) 20,000 Hz - answer b.) 24,000 Hz
The sequence of numbers that make up the digital signal is called the
a.) binary code
b.) analog
c.) sampling rate
d.) digital code - answer d.) digital code
Which of the following is NOT one of the ways digital codes can be used?
a.) helps us identify the location in a stored/filed memory
b.) it can represent a signal
c.) allows me to perform operations on the signal itself so I can amplify it,
equalize it, multiply it
d.) helps to identify whether or not someone has hearing loss - answer d.)
helps identify whether or not someone has hearing loss
Which of the following is an advantage that digital signals have over
analog signals?
a.) digital signals allow for the signal to be manipulated
b.) digital signals only allow the user to amplify all noises occurring
, c.) digital signals are processed faster than analog
d.) digital signals are more accessible than analog - answer a.) digital
signals allow for the signal to be manipulated
Every natural signal can be converted into a ____________
a.) sound
b.) pattern of letters
c.) sequence of numbers
d.) stimulus - answer c.) sequence of numbers
True or false: one way that digital code can be used is by allowing us to
perform operations on the signal such as amplifying it - answer true
True or false: every time point is being processed when there is an analog
signal - answer true
True or False: digital signals are continuous and are happening in real-
time - answer false- analog signals are continuous and happen in real time
whereas digital signals are an approximation of analog time and are
snapshots
true or false: autotune, snapchat filters that alter your voice, computers,
and apps are examples of modern technology where digital signal
processing can be found - answer true
True or False: electrical operations are done on a digital signal - answer
false: mathematical operations are done such as addition, subtraction,
and multiplication
List the 3 ways digital code can be used - answer 1.) Can represent a
signal
2.) allows me to perform operations on the signal itself so I can amplify it,
equalize it, multiply it, etc...
term-93.) helps us identify the location in a stored/filed memory
