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 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?

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.
Light wave is composed of two components an electrical component and a component?
the answer is: magnetic...magnetic and electrical
Which characteristic of a wave changes as the wave travels across a boundary between two different media?
The essential characteristic that changes is the speed of the wave. The wavelength also changes. Amplitude and polarization can change. What does not change is the frequency.
What are the different Types of radar?
radars are of two types pulsed and continuous wave radar. pulsed radar has its carrier pulse modulated used for detecting stationary objects continuous radar uses direct sine wave for transmitting and is used for moving targets there are types such as weather, and aircraft.
Why is light called electromagnetic radiation?
Light is known as electromagnetic radiation because it has two complementary components which were found to be a magnetic field wave in synchronous motion with an electric field wave.
