Select the correct statement(s) regarding antenna and RF wave polarization.

Serggg [28]3 years ago

Answer:

D

Explanation:

A. Polarization is simple for most antennas to determine. It is only on the same level as the antenna components. A vertically polarised antenna (that is one with vertical elements) is better received and a horizontal antenna is equally provided with horizontally polarised signals.

B. The left-hand circular polarization is named if the electric chambers vector rotates counter-clockwise as far as they are from the antenna.

The right-hand circular polarisation is named as the electric field vector rotates counter-clockwise as far as it gets from the antenna.

It then goes without stating the polarisation on the right hand is orthogonal to the left.

C. signals of the same frequency can be transmitted together in an non-interfering manner as long as their polarizations are orthogonal to one another. This too a correct statement.

should variables that contain numbers always be declared as integer or floating-point data types? why or why not? name potential
Stells [14]

No, it is not necessary that variables that contain numbers should always be declared as integer or floating-point data types.

It is not necessary that variables that contain numbers should be declared as integer and floating point data types. Because number can be declared with different data types.  As we know that data type is a vital aspect in programming. It describes the type of a value that is contained in a variable. It is the data type based on which memory is allocated to a number or any type of variables.

Numbers can be whole decimal/fractional, signed, unsigned, small, and long. Simply, they exist in a variety of values. According to their values range, the amount of memory is reserved.

Different programming languages offer different data types to store numbers, depending on their types and size. Let’s consider some examples of data types used in programming languages in order to declare variables holding numbers.

  • In Python int, float, and complex are the data types used to declare number type variables.
  • SQL uses INTEGER, SMALLINT , BIGINT , NUMERIC() , and DECIMAL() data types for numbers.
  • To deal with number type variables, Java has six predefined data types, such as int, long, short, byte, float, and double.
  • JavaScript uses a single data type called 'number' to declare numbers.
  • In C++, two fundamental data types, int and float, are used to represent numeric variables. But C++ is not only limited to these two data types. The data type char can also store numbers. Other data types for declaring numbers as variables are derived from int, float and char, such as short int, long int, signed int, unsigned int, double, long double, signed char, unsigned char etc. etc.

So in concluding remarks, declaring a number type variable is not only limited to using integers and floating-points data types. Rather it entirely depends on the respective programming language, and size and type of the number to be stored in the variable.
