Definition
Obstruction and Pitot Tube 


Term

Definition
A data value can be determined at any time and at any resolution 


Term

Definition
Data which is sampled at discreet time intervals at values mapped to a discreet scale. 


Term

Definition
The value between successive bit representations (Interval) 


Term
Operational Amplifications (OpAmp) 

Definition
Integrated circuit chip with signal conditioning capabilities 


Term

Definition
The factor of amplification between input and output 


Term

Definition
Gives us guidelines on how to time our samples to accurately describe our original signal 


Term

Definition
The number of sample data points collected over a certain time interval 


Term

Definition
Signals which are constantly changing in time. 


Term

Definition
A signal is composed of many super imposed, periodic signals of different frequency 


Term

Definition
Are false frequencies that appear in the output data, simply artifacts of the sampling process. [if not sampled right a 10 Hz frequency could appear like a 20 Hz frequency.] 


Term

Definition
We can avoid aliasing by setting our sample rate to twice the highest frequency of the system [also called Nyquist Frequency], we can also set up a low pass filter [anti aliasing filter] to clean up our data output. 


Term

Definition
It is the range of frequency which make it through the filter. 


Term

Definition
Select which parts of the signal are allowed to pass 


Term

Definition
Is twice the sampling frequency 


Term
The EulerBernoulli equation... 

Definition
Gives the relationship between load and transverse deflection of a beam 


Term

Definition
Gives a relationship between pressure difference and velocity 


Term

Definition
Converts a signal from a function of time to a function of frequency 


Term

Definition
Describes the amount of delay between the output and input 


Term

Definition
Gives the frequency response of a system, Includes both the gain and phase of a system and Can be generated by evaluating the transfer function of s=jw 


Term
Difference between analog and digital data collection: Value representation 

Definition
In analog technology the information is translated into electric pulses of varying amplitude. In digital technology, translation of information is translated into binary format (zero's and one's) where each pit is representative of two distinct amplitudes. 


Term
Difference between analog and digital data collection: Time representation 

Definition
An analog system the time (and or rate is constant) graphically it can represent with a horizontal line. The digital time is represented by a sloped line because there are "steps" where the signal read must be connected.
