- 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.

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 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.

What is the role of a G-protein?
They initiate signal transduction which consists of converting extracellular hormone signal to intracellular signal that creates an action.

What role do dendrites play in transmission at chemical synapses?
Dendrites are the beginning of action potentials as they are formed and then propagate through a neuron. At the synapse, the dendrites receive the incoming signal from neurotransmitters released at the terminal of the previous neuron.

What is the meaning of receiver in communication?
In communication, a receiver is the person or device that receives and interprets the message sent by the sender. The receiver plays a crucial role in the communication process by decoding the message and providing feedback or response to the sender. Effective communication requires clear and accurate message transmission from sender to receiver.

What is the role of multiplexers in signal transmission?
A multiplexor is used to encode multiple input signals for transmission over a single channel. This works because the bandwidth of the output channel is higher than the bandwidth of the input signals, allowing the input signals to share the output channel. At the other end, a de-multiplexor decodes the channel and decodes the individual input signals.
