If you have a constant sweet taste in your mouth, itâs possible you have taste impairment, meaning thereâs a problem with your ability to taste. There are many reasons for taste impairment, including a nasal infection, cold, or flu.
Discrete vs. Continuous Variables. Quantitative variables can be further classified as discrete or continuous. If a variable can take on any value between its minimum value and its maximum value, it is called a continuous variable; otherwise, it is called a discrete variable.
For functions that vary with time, let s(t) be a continuous function (or signal) to be sampled, and let sampling be performed by measuring the value of the continuous function every T seconds, which is called the sampling interval or the sampling period. Then the sampled function is given by the sequence: s(nT), for integer values of n.
