What is relationship between RF transmitter power and distance?
Wiki User
∙ 14y ago
The general relation between distance (d) of a Tx and its power (P) is given by: E=[(30P)^0.5]/d where E stands for the sensitivity of the transmitter in V/m (Volts per meters). E can be assumed 20 uV/m for frequencies below than 200 MHz.

Why is it desirable to have the modulation index of an AM signal as large as possible without overmodulating?
It uses the maximum power available to the transmitter and makes the signal more readable at a greater distance.
What are the function of transmitter?
function of transmitter:-1. generate a signal of desired correct transmitting frequency2. modulation3. power amplification
What is the Relation between power factor and slip?
inversely proportional relationship
How do you charge a Griffin itrip transmitter?
A Griffin itrip transmitter uses the power supply provided by your Ipod, so you are using that battery. There is no battery source in the Itrip I own.
What is the relationship between the total power supplied and the power consumed by the individual resistors in a parallel circuit?
power supplied=sum of powers delivered to individual elements
How much energy does radio waves carry?
that depends mostly on the transmitter power and the square of the distance from the transmitter.
What is the relationship between the working distance of an objective lens and its magnification power?
the working distance decreases as the magnification increases
C Calculate the power flux density in free space when the transmitter gain Gt is 25 if the effective Isotropic radiated power of the transmitter is 300kw and the intrinsic impedance of the transmitter?
Power Flux density is a function of distance from the transmitter so: PFD(r) = 300kW*25/(4*PI*r^2) when r is in meters the value is in kw/m^2
When was Tower of Power - transmitter - created?
Tower of Power - transmitter - was created in 1988.
Relationship between language and power?
Language is a tool that can be used to assert power dynamics in society. The dominant group often sets the standards for language use, which can marginalize other groups. Control over language allows for the shaping of narratives, shaping people's perceptions, and maintaining power structures. Power can also dictate whose language is centered and valued in a given context.
What is the relationship between language and power?
Language and power are closely intertwined as language can be used to shape, influence, and maintain power dynamics. Those who control language can control narratives, shape perceptions, and influence how individuals think and behave. Language can also be used as a tool for empowerment, resistance, and liberation by marginalised groups to challenge existing power structures.
How does the field strength of a standard broadcast station vary with distance from the antenna?
The simplest answer to this question would be that in free space the path loss between the transmitter and the receiver would equal (4 * pi * the distance in meters * frequency in hertz / the speed of light in meters per second) to the power of 2. If you know the power radiated from the transmitter, you can calculate the signal strength at a receiver a given distance away. Since free space only exists in theory, formulas for real scenarios get more complex from here but this is a start.
How does Amy Tan use dialogue to establish the tense relationship between the narrator and her mother?
Amy Tan uses dialogue in a fragmented and terse style to show the tension between the narrator and her mother. Through their interactions, the power dynamics and emotional distance between them are revealed, creating a sense of conflict and unease in their relationship. Tan's use of dialogue highlights the miscommunication and underlying emotions that contribute to the strained relationship between the characters.

What is the relationship between a power supply and a motherboard?
engaged
What is the Mathematical relationship between electrical power and the number of coils of wire?
There is none. There is a relationship between voltage and current and turns ratios in a transformer. But this rule remains - power in = power out. You don't get anything for free.
