What are composite signals why you needed?
In case of TV broad casting, the Video Signal is not transmitted alone, but it accompanied by a number of other signals or pulses, which help the exact reproduction of the picture at the receiving end. These pulses include Blanking Pulses, Synchronizing pulses and Equalizing pulses. A combination of Picture signal and other Controlling signal or pulses is called Composite Signal. Thus Composite Video Signal may consist of Following Parts.Picture information (Data)Blanking Pulses (Delay Pulses)Vertical and Horizontal Synchronizing Pulses (controlling Pulses)Generally,A Combination of Data and Other Controlling Signal is Called Composite Signal .
How can you convert the digital signal given on the speedometer in the car into radio waves which can be received some where else?
First of all digital signal cant be transmitted wirelessly. digital signal can only be transmitted through optical fibre in the form of pulses. so we have to convert digital signal to analog form with the help of DIGITAL TO ANALOG CONVERTOR ( D TO A CONVERTOR). Then this analog signal should be super imposed on carrier signal called MODULATION. modem can be used for that. then that signal can be transmitted to the air through alloted band width like cellular system with the help of transceiver. at the reciveing end we can demodulate the signal with the help of modem & can convert it back to digital form through A TO D CONVERTOR.
When several signals can be transmitted at once it is called?
When several signal transmitted simultaneously. this is called multiplexing of signals.many signal are combined into one and then they transmitted.
What type of modulation produces pulses whose duration is proportional to the amplitude of the intelligence signal?
Pulse-Amplitude Modulation
What wave is combined with another analog signal to produce a unique signal that gets transmitted from one node to another?
Carrier

What is the difference between information and signal?
Information refers to data that has been processed and organized to convey meaning or knowledge, while a signal is a physical representation of information that is transmitted through a medium such as sound waves or electrical pulses. In other words, information is the content being communicated, while a signal is the form in which that information is transmitted.
How is FM transmitted?
the digital signal is converted to analog signal after using by transmitted antenna

How is A Picture in TV-Transmisson Is Transmitted?
In TV transmission, a picture is converted into an electrical signal through a process called scanning, where a camera captures the image and breaks it down into pixels. These pixels are then encoded into a signal that can be modulated and transmitted over the airwaves or via cable. At the receiving end, the signal is demodulated and decoded, reconstructing the original picture for display on a television screen. This process occurs rapidly, typically at rates of 30 frames per second or higher, to create smooth motion.
When several signals can be transmitted at once it is called?
When several signal transmitted simultaneously. this is called multiplexing of signals.many signal are combined into one and then they transmitted.
What is signal that consists of electrical pulses that represent bits grouped into bytes?
digital
What the purpose of given a clock in PCM?
In Pulse Code Modulation (PCM), a clock signal is essential for synchronizing the sampling and reconstruction of the audio or data signal. It ensures that the sampling occurs at regular intervals, allowing for accurate representation of the original signal. The clock also helps in maintaining the timing of data transmission, enabling the receiver to correctly interpret the sequence of coded pulses. Overall, the clock plays a critical role in achieving reliable and high-quality digital communication.
How are analog signals transmitted-?
Analog signals are transmitted as electrical waves.
Is this a true statement An analog signal consists of individual electrical pulses that represent bits grouped together into bytes?
no. The answer is digital signal.
What does the flashing signal in the picture indicate?
The flashing signal in the picture indicates a warning or alert.
What is RZ Signal?
Return to ZeroA type of digital signal where 1's and 0's are pulses of opposite polarity, but between each bit the line returns to the zero (ground) state. It is rather inefficient in terms of bandwidth/data rate, as each bit transmitted uses two baud (i.e. state changes).
