|
|
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
|
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

|
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. |
