9
New cards
data

10
New cards
physical
analog signals are something that is
11
New cards
period
the time for a signal to repeat itself
12
New cards
frequency
the inverse of a period, and the number of times a signal repeats itself in a period
13
New cards
amplitude
the y-value at a given time point
14
New cards
peak to peak amplitude
largest value - smallest value AKA range
15
New cards
duration
how long the sample takes to complete
16
New cards
2^N (N = number of bits)
how would you determine the number of codes
17
New cards
same analog signal
different excitation voltage/full scale, you want to make this very small
18
New cards
excitation voltage / full scale
the total range available to sample
19
New cards
Bits
number of binary digits allocated to ADC
20
New cards
codes
number of bins to split range into
21
New cards
Q = full scale / # of codes
how would you calculated resolution (Q)
22
New cards
V/Code
what units does resolution use
23
New cards
aliasing
misrepresenting an analog signal from under sampling
24
New cards
fs > 2 fmax
nyquist sampling theorem says to preserve frequencies where ________. this helps lose peak amplitudes
25
New cards
5-10 fmax
a good practice would be to sample at a fmax of what
26
New cards
218 Hz
if a signal was sampled at 437 Hz, what is the highest frequency content possible in this signal (round to nearest Hz)
27
New cards
0.000122 V/Code
What is the amplitude resolution of a collection setup using a(n) 14 bit A-D card and a Full-Scale Voltage of 2 volts?
28
New cards
quantization error
misrepresenting an analog signal by not having enough bits in the AD card
29
New cards
clipping
losing signal amplitude from insufficient excitation voltage
30

output/calibrated
to find the slope or calibrate a force transducer, what is considered the y value
31
New cards
input/raw
to find the slope or calibrate a force transducer, what is considered the x value
