Can you have a radio signal underground?
Yes, you can however the distance that a signal may be travel depends on the power and frequency of the signal. For signals at the same power a lower frequency signal will travel further.
What are advantages and disadvantages of multistage amplifier?
to amplify a small signal to sufficient level,so that it can travel to a large distance from first stage till the last stage
What distance can a signal travel on a fiber optic cable?
100m
Is the maximum distance a signal can travel equal to a segment's maximum length?
It is true. The book says "The maximum distance a signal can travel and still be interpreted accurately is equal to a segment's maximum length. Beyond this length, data loss is apt to occur."
Technology to communicate from a distance?
Anything that can travel the distance without being distorted. The faster the signal travels the better useful the technology is. Common technology is: * Radio waves * Light * Electrons and electric potential (Electricity) * Sound * Sending a letter
What are the advantages of tree network?
Central hub (repeater) increases the distance a signal can travel between devices.
What is the maximum distance a signal can travel and still be interpreted accurately is equal to a segments maximum length?
True
What country does the word taxi come from?
It comes from the French word taximetre which was a device used to calculate the cost of travel, based on the distance of the journey and how much time it took to travel that distance.
IF the frequency is maximum then the signal will far awy or near?
higher frequencies attenuate more the further distance they travel.
What does radar measures?
It measures the time it takes for a radio signal of a particular frequency to travel to a target and back. It also measures the strength of the signal when it returns. Based on the travel time of the signal, the radar can measure the distance of the target. Once the radar receives the 2nd signal, it can calculate the velocity of the target. The strength of the signal can be used to determine the size of the target.
How does sound travel electronically?
An electronic device converts the sound waves into a digital signal/code that is then transported by microwaves or radiowaves, until it reaches another device that converts that code back into a soundwave.
Which topology connects each device to a neighboring device?
Ring - A ringtopology connects neighboring nodes until they form a ring. Signals travel in one direction around the ring. In ring topologies, each device on the network acts as a repeater to send the signal to the next device
