What else can I help you with?
What piece of equipment acquires a signal from a communication medium and recovers the original information signal?
modem
What is the reason of using aperiodic digital signal in data communication?
bjbl,
What is meant by a bandpass signal?
Band pass refers to a specific range of frequencies requires for transmission of a signal over a appreciable distance for effective communication by applying special modulation techniques for effective transmission of a signal.
What does a balanced modulator produce?
Please answerin the case of communication , a balanced modulator is used to suppress the carrier from a conventional amplitude modulated signal
What are Disadvantages of digital control?
Unwanted Errors of precision when the analog signal is converted into a quantized, sampled digital signal. The same error arises when the digital signal is then converted into an analog signal for the plant to use.
What is the signal plan?
A "signal plan" is typically a document that outlines how signals are used or managed, whether in traffic control or communication systems. It specifies signal timings in traffic or signal allocation in communication networks.
Which signal is used in communication?
micro wave is used in cell phone communication.
What amplifies the communication from a signal molecule?
penis
Which is not part of the description for communication?
learning a signal
What terms describes a chemical signal made in sweat glans?
The term that describes a chemical signal made in sweat glands is "pheromone." Pheromones are chemical substances released into the environment that can influence the behavior or physiology of other individuals of the same species, often playing a role in communication related to mating, territory, or social interactions. They can be found in various bodily secretions, including sweat.
Data communication for signal characteristics?
past present and emerging developments in signal characteristics?
Where does noise enters in a communication system?
Noise may interfere with signal at ant point in a communication system.The noise has its greatest effect on the signal in the channel.
What are the differences between low attenuation and high attenuation in terms of signal strength in a communication system?
Low attenuation refers to a situation where the signal strength remains strong over long distances, resulting in minimal loss of signal quality. High attenuation, on the other hand, indicates a significant decrease in signal strength over distance, leading to potential loss of signal quality.
Why the received signal in analog communication is distorted by the channel noise than that of digital communication?
If an RF signal is AM modulated with a analogue signal any noise will add or subtract to the amplitude of the RF signal and will be present in the audio signal after detection, also will the noise add itself to the audio signal, where as in digital communication a slight variation in the amplitude of the signal is of no concern because you only work with ones and zeros, it's high or it's low
A what amplifies the communication from a signal molecule?
A receptor amplifies the communication from a signal molecule by triggering a series of intracellular signaling events upon binding to the molecule. This signal amplification allows for the coordination of complex cellular responses to the original signal molecule.
What is the formula for calculating the phase of a signal in a communication system?
The formula for calculating the phase of a signal in a communication system is phase arctan(imaginary part / real part).
What takes place a signal travels from one animal to another and the receiver of the signal responds?
communication
