What is a constant signal?
A constant signal has zero frequency, while a signal that changes very fast over time has high frequencies. Clearly, the higher the frequencies in a signal, the more samples would be needed to represent it with no loss of information thus requiring that Ts be small.
How do you detect a signal?
With an LTC1164-8, signal detection is accomplished by selecting a very narrow signal detection band around the frequency of the desired signal, which is defined as fCLK divided by 100 (fCLK is the clock frequency of the LTC1164-8), and by selecting the filter gain by choosing the value of a resistor.
How to do signal detection in pharmacovigilance?
Quantitative signal detection is most commonly done through disproportionality statistics: the ratio of the proportion of spontaneous ICSRs of a specific drug-event combination to the proportion that would be expected if no association existed between the product and the event.
What is an example of signal detection theory?
(a) Introduction to signal detection theory. A simple example of using SDT in experimental psychology is when testing the ability of a subject to detect a short tone pip (beep) in a background of white noise ('ssss…'; [1]). Over repeated trials subjects are required to decide whether there was a tone present or not.
