Explanation: **The transmitter-receiver combination in the satellite** is known as a transponder. The basic functions of a transponder are amplification and frequency translation. The reason for frequency translation is that the transponder cannot transmit and receive on the same frequency. 3.

……………… is the middle value in the distribution when it is arrangedin descending or ascending order.

Q. | Which is type of frequency distribution? |
---|---|

A. | Continuous or grouped frequency distribution |

B. | Discrete or ungrouped frequency distribution |

C. | Cumulative Frequency Distribution |

D. | All of the above |

In telecommunication, Carson's bandwidth rule **defines the approximate bandwidth requirements of communications system components for a carrier signal that is frequency modulated by a continuous or broad spectrum of frequencies rather than a single frequency**.

A Frequency curve is **a graph of frequency distribution where the line is smooth**. It is just like a frequency polygon. In the polygon is line is straight, but in the curve the line is smooth. It is an area diagram. It is the graphical representation of frequency distribution.

What is the symbol of frequency? The symbols most often used for frequency are **f and the Greek letters nu (ν) and omega (ω)**. Nu is used more often when specifying electromagnetic waves, such as light, X-rays, and gamma rays.

There are four types of frequency distributions: **ungrouped frequency distributions, grouped frequency distributions, cumulative frequency distributions, and relative frequency distributions**. A frequency distribution table represents how many each item in a data set occurs.

CDMA stands for **Code Division Multiple Access**. CDMA (Code Division Multiple Access) uses a digital modulation technique called Direct Sequence spread spectrum which spreads voice data over a very wide spectrum using a user or cell-specific pseudo-random codes.

In the case of FM, **Bandwith is large and noise immunity is high** that's why it is used in satellite communication.

Carson's rule **gives the estimation of the bandwidth of an FM system**. This rule states that the bandwidth of an FM system is double the sum of the maximum frequency deviation and the highest modulating frequency f_{m}.

As a statistical tool, a frequency distribution provides a visual representation of the distribution of observations within a particular test. Analysts often use a frequency distribution **to visualize or illustrate the data collected in a sample**.

Frequency distribution, in statistics, **a graph or data set organized to show the frequency of occurrence of each possible outcome of a repeatable event observed many times**.

Frequency Modulation is **a modulation in which the frequency of the carrier wave is altered according to the instantaneous amplitude of the modulating signal, keeping phase and amplitude constant**.

The correct answer is **88 - 108 MHz**. The VHF (very high frequency) FM channels range from 87.8 to 108.0 MHz, proving an overall bandwidth of 20.2 MHz.

**Class Interval = Upper-Class limit – Lower class limit**. In statistics, the data is arranged into different classes and the width of such class is called class interval. 1^{st} lesson free!

A frequency polygon is **a graph that represents frequency distribution**.

Explanation: **The transmitter-receiver combination in the satellite** is known as a transponder. The basic functions of a transponder are amplification and frequency translation. The reason for frequency translation is that the transponder cannot transmit and receive on the same frequency. 3.

In theory, the sidebands are **infinite** in number, but in practice, most of the energy in an FM signal fits into an RF bandwidth equal to 2 x (highest modulating frequency + peak deviation). The strengths of the different sideband pairs in an FM signal follow Bessel functions.

Students will begin by thinking about what management means to them, and work toward building a comprehensive understanding of the specific types of responsibilities that fall under the five functions of management framework: **decision-making, planning, staffing, directing and controlling**.

Basic Functions of Computer. There are four basic functions of the computer: **Input, Processing, Output, and Storage**.

The four basic functions of a computer are: **input, storage, processing, and output**.

Nutrients are **substances required by the body to perform its basic functions**. Nutrients must be obtained from our diet since the human body can not make them. Nutrients have one or more of three basic functions: they provide energy, contribute to body structure, and/or regulate chemical processes in the body.
