Splitter
The sampling rate must be at least double the highest frequency component of the modulating signal in order to avoid frequency aliasing.
if the sampling rate is twice that of maximum frequency component in the message signal it is known as nyquist rate
Demodulation takes place to extract the low-frequency signal from the high-frequency carrier, using a nonlinear process that produces components at the signal frequency. The LP filter is used to eliminate the high-frequency carrier component from the signal so that it does not cause problems at a later stage in the amplification of the signal.
No, it just combines the selected inputs to form a single output.There are now both analog and digital mixers, but on a mixer of a given type whatever signal type goes in comes out.You need a converter to convert signal types.
Ripple.
when some of the component are being delayed compared to other component, so the resulting signal will be different from original signal.
The component that gets amplified will depend on the type of amplifier we are using. In general the voltage component of the signal gets amplified.
A composite signal is a mux or a bus signal. These can be thought of as a collection of other component signals.
Jam signal
A digital signal is actually a complex signal. Consider the horizontal part of a digital signal as a component with 0 frequency and the vertical part of the signal as the component of infinite frequency. Also, consider the change from the horizontal to vertical as all the frequencies. Then we can claim that a digital signal is complex signal with frequencies from 0 to infinite.A digital signal is a composite analog signal with an infinite bandwidth.
A single cable carrying video will be carrying a composite video signal. This signal has brightness and two color signals encoded into a single signal. To generate a component signal (YPbPr)a video decoder is required. They are available from many sources from low cost domestic units to stunningly expensive broadcast models. The better the decoder, the better the resulting image. It is very important to understand that a composite signal has suffered losses because of the encoding. Decoding the signal to component does not restore that quality. Component interfaces can handle high definition as well as standard definition signals. Decoding a composite signal will result in a standard definition signal. Connecting it to a high definition input will not result in a high definition signal. Normally, the only reason to decode the signal to component is to interface to a device that only accepts component signals.
how do we protect our cable network from signal jammer
Component video is a video signal that has been split into multiple component channels. There are two types of it, RGB analog component video and Luma-based analog component video.
Network Management signal
A 50 Ohm Terminator is used at each end of the network to prevent signal reflections.
No. The transmitter of a radio station emits an electromagnetic signal that has been modified by sound waves that were converted into an electronic signal.
S-Video is a type of composite video signal. The 4 pins are Chrominance, Luminance, and 2 grounds. Your standard composite video cable combines Chrominance and Luminance into one signal, which is then separated again by the TV. An S-video cable removes this step. The "y, pB, pR" cable set is known as "component" video. this cable goes one step further than S-Video, breaking down the Chrominance signal to individual colors, using Red (pR), Blue (pB) and Luminance (y). The TV then uses additive and subtractive methods to determine Green.
