What is the difference between continuous and analog signal?
A continuous signal cannot be stored, or processed, in a computer since it would require infinite data. Analog signals must be discretized (digitized) to produce a finite set of numbers for computer use. When analog signals are brought into a computer, they must be made discrete (finite and countable).
What is the definition of continuous signal?
A continuous signal is a continuous function of time defined on the real line R denoted by. s(t), t is time. The signal can be complex valued. A continuous signal is called an analog. signal.
Is audio signal discrete or continuous?
Sound Signals Sounds are typically measured via transducers that convert air vibrations into electrical signals. Electrical sound signals are continuous-time representations of air pressure variations. These representations can subsequently be stored and/or processed using signal processing techniques.
What are the types of continuous & discrete time systems?
There are two types of signals: continuous-time signals and discrete-time signals. Continuous-time signal: the variable of time is continuous. A speech signal as a function of time is a continuous-time signal. Discrete-time signal: the variable of time is discrete.
Is time a discrete or continuous variable?
Time is a continuous variable. You could turn age into a discrete variable and then you could count it. For example: A person’s age in years.
Is Money discrete or continuous?
A continuous distribution should have an infinite number of values between $0.00 and $0.01. Money does not have this property – there is always an indivisible unit of smallest currency. And as such, money is a discrete quantity.
Is blood type continuous or discrete?
Blood type is not a discrete random variable because it is categorical. Continuous random variables have numeric values that can be any number in an interval. For example, the (exact) weight of a person is a continuous random variable. Foot length is also a continuous random variable.
Is blood pressure discrete or continuous?
Is blood pressure an example of continuous or discrete data? Blood pressure is an example of continuous data. Blood pressure can be measured to as many decimals as the measuring instrument allows.
Is gender a discrete or continuous variable?
On purpose, I made it sound distinct that a variable is either discrete or continuous….Variable Reference Table : Few Examples.
Variable | Variable Type | Variable Scale |
---|---|---|
Gender | Discrete | Categorical |
Gender as Binary 1/0 Coding | Discrete | Categorical |
True/False | Discrete | Categorical |
Phone Number | Discrete | Nominal |
Is heart beats per minute discrete or continuous?
Variables such as heart rate, platelet count and respiration rate are in fact discrete yet are considered continuous because of large number of possible values. Only those variables which can take a small number of values, say, less than 10, are generally considered discrete.
Is death a continuous variable?
For example, “male” or “female” are categorical discrete data values. Mortality (eg. 20 patients dead at 6 months) is an example of numerical discrete data values. Continuous data: when the variable is unrestricted and can have any value from a potentially infinite range, eg.
Is birth rate continuous or discrete?
But if the adults breeding in one season rarely or never survive to breed in the next has an important effect on their dynamics. In discrete growth we consider birth rate and death rate of the organisms.
Is religion discrete or continuous?
discrete (categorical) variables can be further classified into: ➢ nominal variable: no natural ordering between categories (e.g., religious affiliation, mode of transportation, favorite type of music, …) (e.g., size of automobile, social class, political philosophy, patient condition, …)
Is Social Class A discrete or continuous variable?
Any measurement of number of people, for example, the number of students in a class, is a discrete variable – each student is a distinct human being, and the number of students can be counted.
Is blood sugar level discrete or continuous?
For example, the concentration of glucose in the blood is a continuous quantity. Even if the instrument you are using rounds off values to whole numbers, these quantities are still continuous; ie, not countable.
Is discrete data quantitative or qualitative?
Quantitative Data are numbers: heights; weights; speeds; number of pets owned; years; etc. Qualitative Data are not numbers. Discrete Data are numbers that may take on specific, separated values. For example, when you roll one die, you get 1, 2, 3, 4, 5, or 6.
