- The Role of modulation in signal transmission varies because of what type of signal should be modulated.Then how long it should be travel in air.All these points are considered, when we go before modulation.
- Suppose we are transmitting vedio signal means it should be only Amplitude Modulated signal.If we transmitting audio signal means it should be Frequency Modulated Signals.
- So the Role of the modulation is varies in signal transmission.

Why Microwave SDH Radio can not go beyond STM-1 bandwidth?
AnswerOfcourse BW will play its own role. But, present situation limitation of ADC speed, signal processing chip speed limitation and high data rate modem implementation complexity will play the major role.In future, if any one invent modulation with magnetic force, it may be possible.
What is the role of clock generator in microprocessor?
The clock signal in a microprocessor allows synchronization of several components of the microprocessor. The correctness of the computation of the microprocessor depends upon efficient and balanced distribution of the clock signal. The clock generator generates the clock signal.
What is the purpose of a DSP processor?
A DSP processor is otherwise known as a digital signal processor, whose role is to convert analogue signals by reading them by measuring, filtering and compressing them. This stream of features are known as algorithms, when mathematical operations have to be quickly performed.

What is a clutch brake on a heavy duty truck transmissions?
A clutch brake is a circular disc with a friction surface that is splined to the input shaft of the transmission between the release bearing and transmission. Its purpose is to slow and/or stop the input shaft from turning to allow initial forward or reverse gear engagement in non-synchronized transmissions. It helps prevent premature wear of the internal transmission parts during those initial shifts. To understand this in more detail, let's consider what is going on when a heavy truck transmission is shifted from neutral to first or reverse. When a truck is in neutral and the clutch pedal is not depressed, the master clutch is engaged. This causes power from the engine to drive the transmission input shaft, resulting in rotation of some shafts and gears in the transmission. However, the gears aren't engaged or meshed in a way that transmits power to the drive shaft. In other words, parts of the transmission are just idling but spinning. When the clutch pedal is depressed, it moves the release or throw-out bearing toward the transmission and away from the flywheel. This unloads the springs in the master clutch, releasing the master clutch and decoupling the flywheel from the transmission output shaft. Without the engine driving the transmission input shaft, the spinning shafts and gears in the transmission start to coast down. However, it would take a long time for these rotating masses to slow down, because they have a lot of mass and the only thing that is slowing them is gear and bearing drag. If everything is properly adjusted, the master clutch is opened or released when the pedal is depressed about half way or so. If there's no clutch-brake, and you then shift into first or reverse, the rotation of gears in the transmission won't all be the same on a non-synchronized transmission, and then the gears can clash or make a "thunk" as gears that are spinning are meshed with gears that are not spinning. Over time, this can wear or even damage the gears. When a clutch-brake is installed, pushing the clutch pedal all the way to the floor pulls the release bearing even further away from the master clutch toward the transmission, which eventually squeezes the clutch-brake disc between the release bearing and the transmission case. Friction between these parts then slows and soon stops the transmission input shaft from rotating. Now, gears can be moved into mesh in the transmission and there might be a bit of noise because the teeth aren't perfectly aligned, but they won't be rotating. If you time everything just right, you'll make the shift from neutral to first or reverse just as the gears are almost stopped, but not quite. A little rotation helps ease the meshing and can almost eliminate noise or "thunk" sounds. The clutch-brake is unusual because it always picks up grease from the release bearing. Modern clutch-brakes are designed to operate with grease, and they even require greasing or oiling before installation. Clutch-brakes fail for two reasons. First, over time, the friction material will wear out. At some point, there will be metal-to-metal contact in the "sandwich" consisting of the bearing, clutch-brake plate, and the transmission cover. This might still slow the gears, but it can cause damage to the bearing or the transmission cover. It's also possible that the release bearing won't be able to move far enough toward the transmission to squeeze the disc, and the clutch-brake won't slow down the transmission shaft because there won't be friction in the "sandwich." If you keep the pedal linkage properly adjusted and periodically grease the release bearing and clutch-brake disc, the disc can last for a long time. However, the most common cause of clutch-brake failure is depressing the clutch pedal all the way to the floor when shifting during a range change--when the truck is moving. When you do this, you are forcing the little clutch-brake to try and stall the engine and stop the truck! Doing that only one time will often destroy the clutch-brake completely. This can also occur if the pedal linkage isn't properly adjusted and the release bearing squeezes the clutch-brake into the transmission case when making a range gear change.
Define constellation diagram and its role in analog transmission?
A constellation diagram is a representation of a signal modulated by a digital modulation scheme such as quadrature amplitude modulation or phase-shift keying. It displays the signal as a two-dimensional scatter diagram in the complex plane at symbol sampling instants. In a more abstract sense, it represents the possible symbols that may be selected by a given modulation scheme as points in the complex plane. Measured constellation diagrams can be used to recognize the type of interference and distortion in a signal.By: ISRAFIL CSE
What the main function of baseband?
The main function of baseband is to process and control the transmission and reception of digital signals within a communication system. It is responsible for tasks such as converting analog signals to digital, coding and decoding data, and managing signal modulation and demodulation. Overall, the baseband plays a crucial role in enabling efficient communication between devices.

What is difference between modulator and demodulator?
Modulation is used when information is available in analog form that varies the frequency and/or amplitude of a lower frequency wave, depending on the information it carries. The role of modulation is to place this information onto a carrier frequency that can be transmitted more readily and with least loss of information. There are three fundamental types of modulation - frequency modulation, amplitude modulation and phase modulation. In each of these, a carrier frequency is modulated by a lower frequency, to form a modulated carrier wave. 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.

The role of the myelin sheath?
The myelin sheath is a protective covering that surrounds nerve fibers and helps in efficient transmission of nerve impulses. It acts as an insulator, speeding up the transmission of signals along the nerves. Damage to the myelin sheath can result in disruptions in nerve signal transmission and lead to conditions such as multiple sclerosis.
What function does synaptic vesicles containing neurotransmitter?
Synaptic vesicles containing neurotransmitters play a crucial role in communication between neurons. They release neurotransmitters into the synaptic cleft, where they bind to receptors on the receiving neuron, leading to signal transmission. This process allows for the relay of information within the nervous system.
What is the meaning of receiver in communication?
Hi, Receivers normally seperates the source signal from the carrier signal which is used for conveying the source signal to the destination & then the received signal is being amplified for usage.
