What is bandwidth required for AM signal?
With full double sideband AM the bandwidth of the modulated signal is twice that of the baseband information signal. With suppressed carrier single sideband AM the bandwidth of the modulated signal is identical to that of the baseband information signal. With vestigial sideband AM the bandwidth of the modulated signal is somewhere between the above two cases, depending on how much of the vestigial sideband is included.
Can an analog tv receive a digital cable signal?
using two subcarriers and a main carrier signalaudio subcarrier is frequency modulated with audiocolor subcarrier is phase modulated with chromamain carrier is amplitude modulated with sum of video and modulated audio subcarrier & color subcarrier; then lower sideband is suppressed by a filter.closed captions are serial ASCII encoded characters embedded in vertical blanking of video signal
Discussion about amplitude demodulator?
A modulator modulates the carrier frequency, while a demodulator detects the modulation on the carrier wave and recovers the original lower frequency waveform at the destination. For many years the modulated carrier wave was converted to a radio signal. Now it is often an electrical signal which is sent down a teleohone line; the information is usually a set of pulses going between computers. When computers are connected to each other in a two-way conversation, the MOdulator and DEModulator are combined into a single device called a MODEM.
What are the Applications of double side suppressed carrier modulation?
Each of the two sidebands can be modulated independently to give two simultaneous communication channels. There would be no point in radiating the carrier, as it carries no information, and would waste transmitter power.
What are the components of c language?
Compiler and Programmer these are the two components of the C language
What are the two components of light wave?
The two components of a light wave are the electric field and the magnetic field. These fields oscillate perpendicular to each other and to the direction in which the wave is traveling.
What is a wave what are the components of a wave?
A wave is a disturbance that transfers energy through a medium or space. It consists of two main components: amplitude, which is the height of the wave from the resting position, and wavelength, which is the distance between two corresponding points on the wave.
What are the two essential components to create metamorphic rocks?
Heat and pressure are the two key components.
What is difference between modulated wave and carrier wave?
Carrier Wave: A carrier wave is a high-frequency electromagnetic wave that is used as the "carrier" or the base signal in a modulation process. It is typically a pure sine wave with a constant frequency and amplitude. The carrier wave by itself does not carry any information; it serves as a vehicle to carry the information from one location to another. In AM and FM radio broadcasting, the carrier wave is the primary signal transmitted by the radio station. Modulated Wave: A modulated wave is the result of combining the carrier wave with an information signal, such as an audio signal or data. Modulation is the process of varying the characteristics of the carrier wave (either its amplitude or frequency) in accordance with the information signal. There are two common types of modulation: Amplitude Modulation (AM) and Frequency Modulation (FM). In AM, the amplitude of the carrier wave is varied in proportion to the amplitude of the information signal. This variation encodes the information onto the carrier wave. In FM, the frequency of the carrier wave is varied in proportion to the amplitude of the information signal. This variation encodes the information onto the carrier wave. The modulated wave contains the information that needs to be transmitted, and it can be demodulated at the receiving end to retrieve the original information.
What are the two components of a wave of light?
Electromagnetic waves do not require a medium to travel (light, radio).
What is phase discriminator?
A phase discriminator is a circuit or device used to compare the phase difference between two input signals. It is often used in communication systems to demodulate or recover the original signal from a modulated carrier wave by detecting the phase difference between the carrier wave and the modulated signal.
What are the two essential components of life as you know it?
The heart, and the brain.
A two cavity klystron tube is a?
a. velocity modulated tube b. frequency modulated tube c. Amplitude modulated tube d. simple triode
What are the frequency components in an am wave?
An AM wave consists of two frequency components: a carrier wave at the original frequency of the transmitted signal, and two sidebands that are located just above and below the carrier frequency. The sidebands contain the original signal information and are responsible for carrying the actual audio content.
What are the two essential components of innovation?
The two essential components of innovation are creativity, which involves generating novel ideas and solutions, and implementation, which involves bringing those ideas to market or putting them into practice to create value. Successful innovation requires both inventive thinking and effective execution.
Frequency spectrum analysis of AM wave?
An amplitude modulated signal consists of a CW (continuous wave) at the carrier frequency, plus two components for each frequency in the modulating information. The two components are separated from the carrier by a frequency equal to the modulating frequency, with one above and one below the carrier frequency. Thus, the modulating information appears twice in the spectrum of the modulated signal.
What are the two main components of soil?
The two main components of soil are organic matter, such as decaying plant and animal material, and inorganic matter, such as minerals and rocks. These components provide essential nutrients and structure for plant growth.
