New cards
digital signal
stream of numbers called digital code
2
New cards
analog signal
continuous signal created from a sound
3
New cards
how are analog signals converted to digital code
an analog to digital converter (ADC)
4
New cards
sampling rate
number of times/ seconds the magnitude of the signal is measured
5
New cards
nyquist frequency
highest frequency in the spectrum of a signal
6
New cards
what must the sampling rate be to represent the original signal
at least twice the nyquist frequency
7
New cards
digital precision
can be calculated using formula d= 2 to the power of n
8
New cards
what is ‘d’ in digital precision formula
the number of digitized values
9
New cards
what is ‘n’ in digital precision formula
the number of bits
10
New cards
3 bits equal
011
11
New cards
4 bits equal
1011
12
New cards
aliasing error
distortion of a digital signal caused by a sampling rate that is too low
13
New cards
quantization error
difference between actual amplitude of the analog signal and amplitude represented by the digital signal
14
New cards
what can a quantization error be heard as
noise
