How does condenser microphone works?
A condenser is a capacitor and it consist of two plates separated by some insulating material or air the closer the plates to each other the higher the capacitance, a condenser mic is only a capacitor with the one plate mounted so that it can vibrate when you speak into it, as the plate is vibrating it moves closer an further away from the other plate and continually changing the capacitance, this is used in most small FM transmitters to vary the RF frequency because it form part of the tuned LC circuit
What is FM microphone?
FM = frequency modulationThis technology using to make wireless microphones . The essential transmitting circuits will be integrated with the microphones, and there wil be one signal receiver , to be connect to the amblifier instead of conventional cable. so the singer can perform within a limitted area with wireless FM-microphone
What does Armstrong modulator generate?
Armstrong modulator generates FM signals.
Is Armstrong method for FM generation and armstrong phase modulator same?
Since we can generate fm from phase modulation, thus both are related to each other

Why we need high power to generate AM signal and low power to generate FM signal?
The reason FM has lower power and AM has higher power is because the more power that an AM signal has, the farther it will go, but FM does not work that way. AM waves can bounce off of the atmosphere, especially at night. This is the reason that you can hear AM stations from far away at night. FM, on the other hand, can't bounce. FM waves only go in a straight line from the tower and no matter how much power you transmit with, an FM wave will only go a short distance. AM Waves can travel through trees and buildings, and FM can't.
What is narrow band FM and how a narrow band FM generate?
If the modulation index of FM is kept under 1, then the FM produced is regarded as narrow band FM. Lower the modulation index, lower the no. of significant sidebands are produced (with reference to bessel function). So lower the no. of significant sideband, lowerer will be the bandwidth of the resulting FM prduced. Sometimes, Narrow Band FM is regarded as, when the significant energy in FM occupies the same bandwidth as ordinary AM with the same modulating signal.
Can an FM transmitter be used in a car?
Yes. FM transmitters will work with a car stereo.
