Answer:
The answer is 2988 bits per seconds
Explanation:
Solution
Given that:
Bandwidth (B) = 300Hz
Signal to noise ratio (SNR) = 30dB
Now let C = channel capacity
Using Deubel formula we have the following:
SNR db = 10* log (SNR)
30 =10* log (SNR)
So,
SNR =log^⁻1 (3)
SNR = (10)^3
SNR = 1000
Thus SNR =1000
Now
Applying the Shannon's equation
C = B * log₂ ( 1 + SNR)
C = 300 * log₂ ( 1 + 1000)
C = 300 * log₂ (1001)
C = 300 * 9.96
C =2988
Hence the capacity of the channel for teleprinter channel is 2988 bits per second.
Answer:
A key benefit of inheritance is: an object can have several types, it is type compatible with any of its super classes
Explanation:
- Inheritance is one of the fundamental concepts of Object Oriented Programming.
- Inheritance allows classes (derived classes) to inherit the methods and properties of a class (base class).
- The class or classes that inherits the characteristics from another class is called a derived class, child class or sub class. Derived class can also has it own methods and attributes additionally.
- The class whose methods and properties are inherited by the derived class or classes is called a base class, super class or a parent class.
- Benefit of inheritance is that inheritance new objects can take properties of existing objects and an object can have many types.
- Also a child class can inherit from more than one super classes which is called multiple inheritance.
- Multiple inheritance allows a class to implement more than one abstract classes.
- An object can have several types. These types can be of an object's own class and also other types which include all classes that a class inherits.
- If a variable is declared to be the type of super class then value of that variable can refer to any instance that instantiated from any class that inherits that super class. This means that an object is type compatible with an of its super classes.
Answer:
General purpose computers are designed to be able to perform variety of tasks when loaded with appropriate programs, while special purpose computers are designed to accomplish a single task.
Answer:
B) vaporware.
Explanation:
Vaporware is a software or hardware product that is not yet released in the market but has already advertised. This can be the product is probably still under development or it is still in its idea form and not developed at all. Vaporware is a term used in the computer products industry. Products that were announced but missed the released date by a big amount of time can also be called vaporware.
