To receive a Satellite signal, you need a LNB which is attached to your satellite dish--The LNB and dish is determined by which satellite TV service you have--either Dish Network or DirecTV. The satellite dish is pointed in a particular direction to pick up the correct satellite orbiting the sky. You will also need a satellite receiver, which is "wired" to the LNB and also is attached to your television.

What is the blended word for modulation demodulation?
The blended word for modulation and demodulation is "modem." A modem is a device that modulates digital signals into analog signals for transmission and demodulates received signals back into digital form. This process enables communication over various types of networks, such as telephone lines and broadband connections.
What is a block Diagram of facsimile?
A block diagram of a facsimile (fax) machine illustrates the main components and their interactions in the process of sending and receiving documents. Key blocks typically include the scanner, which converts the document into electrical signals; the transmitter, which modulates these signals for transmission over a telephone line; and the receiver, which demodulates the signals back into an image. The output block represents the printer, which produces a hard copy of the received document. This visual representation helps to understand the flow of information and the functional relationships between the components.
Is a moderm converts the digital signals from a computer into signals that can travel over a network?
Yes, a modem (modulator-demodulator) converts digital signals from a computer into analog signals that can be transmitted over various types of networks, such as telephone lines or cable systems. It also performs the reverse function, converting incoming analog signals back into digital form for the computer. This process enables communication between digital devices and external networks.
What does an RF modulator do?
An RF modulator converts baseband audio and video signals into radio frequency (RF) signals suitable for transmission over the airwaves or through coaxial cables. It modulates the input signals onto a specific carrier frequency, allowing them to be broadcasted or transmitted to TVs and other devices that can receive RF signals. This process enables the delivery of content over longer distances and through different types of media. RF modulators are commonly used in television broadcasting and in connecting devices like gaming consoles to older TVs.
What is a vacuum tube that has three electrodes?
A vacuum tube with three electrodes is commonly known as a triode. It consists of a cathode, an anode, and a control grid, allowing it to amplify electrical signals. The control grid modulates the flow of electrons from the cathode to the anode, enabling the triode to function as an amplifier or a switch in various electronic applications. Triodes were essential in early electronics but have largely been replaced by transistors in modern circuits.
What device that modulates outgoing signals and demodulates incoming DSL signals?
DSLAM
How the modem change the analog signal?
MODEM stands for modulator/demodulator. Outgoing it modulates a carrier wave with information and transmits this data on a wire or through the air. When it receives a modulated signal it demodulates the signal and separates out the information.
The device that reconciles the difference between computers and phones is the a.TcpIp b.LAN c.Wand reader d.Modem?
d. Modem It modulates digital signals to analogue signals and demodulates analogue signals back to digital signals.
What Technology used to modify analog signals to make them suitable for carrying data over a communication path?
MODEM (Modulator - Demodulator)modulates Digitals signals to Analog to send over Telephone lines and Demodulates Analog signals in Digital Signals.
Is a standard modem considered to be computer hardware?
Yes. A modem, even a single chip modem, is a hardware device that modulates ("mo") and demodulates ("dem") analog signals for use in digital devices.
What is the blended word for modulation demodulation?
The blended word for modulation and demodulation is "modem." A modem is a device that modulates digital signals into analog signals for transmission and demodulates received signals back into digital form. This process enables communication over various types of networks, such as telephone lines and broadband connections.
Which OSI layer converts bits into signals for outgoing messages and signals into bits for incoming messages?
The OSI layer responsible for converting bits into signals for outgoing messages and signals into bits for incoming messages is the Physical layer. This layer handles the transmission and reception of raw bitstreams over a physical medium, such as cables or wireless signals. It defines the electrical, mechanical, and procedural specifications for transmitting data.
What Following statements accurately describes how a modem works?
A modem (modulator-demodulator) converts digital data from a computer into analog signals for transmission over telephone lines or other communication mediums. It modulates digital signals into analog form for sending and demodulates incoming analog signals back into digital data for the computer. This process enables devices to communicate over various types of networks, such as DSL, cable, or fiber-optic connections. Essentially, the modem serves as a bridge between digital devices and the analog transmission infrastructure.
What hard ware component modulate and demodulate signals and gives there functions?
The hardware component that modulates and demodulates signals is called a modem (modulator-demodulator). Its primary function is to convert digital data from a computer into an analog signal suitable for transmission over telephone lines or other communication mediums (modulation), and to convert incoming analog signals back into digital data for the computer to process (demodulation). This enables effective communication over various types of networks, including broadband and dial-up connections.
Is a modems input or output?
MODEM Stands for MOdulator DEModulator. It acts both as an input & output (SIGNAL) as it converts incoming analog signals to digital and viceversa. Incoming - while downloading. Outgoing - while uploading.
How does an external modem work?
An external modem connects to a computer and a communication line, such as a phone line or cable system, to facilitate data transmission. It modulates digital signals from the computer into analog signals for transmission over the communication line and demodulates incoming analog signals back into digital form for the computer. This process allows devices to communicate over long distances by converting data formats suitable for both the digital realm of computers and the analog nature of communication lines. External modems typically connect via USB or serial ports, providing a bridge between the digital and analog worlds.
What would one use a cell phone amplifier for?
It amplifies the incoming and outgoing signals. This would be used by someone who lived in an area where cell phone reception was poor.
