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
To calculate the admittance if you are given the impedance, you take the inverse of the impedance ( that is 1/z).
The frequency at which the impedance of the circuit becomes zero is known as resonance frequency. Actually at resonance resistance only presence in the circuit. That means the impedance of the inductor and capacitor will automatically vanish.
You can. Give an example, and someone here will help.
By increasing the input impedance of amplifier.
by calculating the loop current
Loading refers to the phenomena that occurs when a load circuit having low effective impedance is connected to a supply circuit having higher effective impedance.
I believe intrinsic impedance is more tied to the medium, thus is defined in terms of magnetic and electric permeability and electrical conductivity, while characteristic impedance is a "wider" look at the impedance. For example, you can calculate the intrinsic impedance of a 18 awg copper wire, or air, or a vacuum. If you wanted to use coax cable with an 18 awg core, you would be looking at the characteristic impedance, not the intrinsic impedance of the copper that will be carrying the waveform.
to calculate and measure the impedance ,admittance is simple
You need to divide the supply voltage by the impedance of the load. The impedance of the load is the vectorial sum of its resistance and reactance, where reactance is proportional to frequency.
There are 3 stages of an FM transmitter which allow you to transmit information over the FM band. These 3 stages need to be integrated into a single circuit to form what is known as a 3 stage FM transmitterA modulator circuit to add the information to be transmitted to the carrier wave produced by the oscillator. This is done by varying some aspect of the carrier wave. The information is provided to the transmitter either in the form of an audio signal, which represents sound, a video signal, or for data in the form of a binary digital signal. In an FM (frequency modulation) transmitter the frequency of the carrier is varied by the audio signal.Many other types of modulation are also used. In large transmitters the oscillator and modulator together are often referred to as the exciter. An RF power amplifier to increase the power of the signal, to increase the range of the radio waves.An impedance matching (antenna tuner) circuit to match the impedance of the transmitter to the impedance of the antenna (or the transmission line to the antenna), to transfer power efficiently to the antenna. If these impedances are not equal, it causes a condition called standing waves, in which the power is reflected back from the antenna toward the transmitter, wasting power and sometimes overheating the transmitter.
It might be. Or it might not. You need to specify the transformer's turns ratio or its impedance ratio, and th eload on the secondary.
That depends on the output impedance. In electronic we use voltage bridging, that is a relative low output impedance to a higher input impedance. Usualy the input impedance is more than ten times higher then the output impedance. An input impedance is called also a load impedance or an external impedance. An output impedance is called also a source impedance or an internal impedance.
