How does the signal noise ratio SNR related to the no of bits in the digital representation?
How does the Signal-Noise Ratio (SNR) relates to the number of bits in the digital representation? generalizes to any system using a digital representation. So, a microprocessor representing values with N bits will have a SNR defined by the above formula.
Which signals are continuous and non discrete?
The function itself need not to be continuous. To contrast, a discrete-time signal has a countable domain, like the natural numbers. A signal of continuous amplitude and time is known as a continuous-time signal or an analog signal. This (a signal) will have some value at every instant of time.
Which is the domain of a discrete function?
The values of x that can be used in a function are called the domain of the function. The domain can either be discrete or continuous. A discrete function would have x-values that stand alone. They do not have an interval around them.
How is a discrete signal similar to a continuous signal?
There are two very similar sounding concepts related to discrete signals. In general terms a discrete signal is continuousin amplitude but is discretein time. This means that it can have any value whatsoever for its amplitude but is defined or measured only at a specifictime.
Which is an example of a continuous domain?
If the domain of a function was the interval from 1 to 2, that would mean that all values between 1 and 2 (such as 1, 1.232, 1.664324, 3/2, 1.1156, 2, etc.) will work in the function. The values outside of the interval such as -3, 7.1, etc. are not to be included in the domain.
Which is an example of a discrete random variable?
And discrete random variables, these are essentially random variables that can take on distinct or separate values. And we’ll give examples of that in a second. So that comes straight from the meaning of the word discrete in the English language– distinct or separate values.
