Why the frequency of voice channel is from 300 to 3400?
The frequency band 300 Htz to 3400 Htz is alloted for voice channel. That's it
What is FM transmitter and what are the different FM transmitters?
FM transmitter : In this case the frequency of a carrier signal is modulated/altered in accordance with that of frequency of modulating signal. TYPES OF FM TRANSMITTER: 1> directly modulated FM transmitter. 2>indirectly modulated FM transmitter. an FM transmitter is a portable device that plugs into the headphone jack or proprietary output port of a portable audio or video device, such as a portable media player, CD player, or satellite radio system. The sound is then broadcast through the transmitter, and plays through an FM broadcast band frequency. Purposes for an FM transmitter include playing music from a device through a car stereo, or any radio.
What is a duplexer?
A duplexer is a device that allows bi-directional (duplex) communication over a single channel. In radar systems, a device that isolates the receiver from the transmitter while permitting them to share a common antenna. Note 1: A duplexer must be designed for operation in the frequency band used by the receiver and transmitter, and must be capable of handling the output power of the transmitter. Note 2: A duplexer must provide adequate rejection of transmitter noise occurring at the receive frequency, and must be designed to operate at, or less than, the frequency separation between the transmitter and receiver. Note 3: A duplexer must provide sufficient isolation to prevent receiver desensitization.Braimah prosper
How an electronic transmitters work?
A transmitter takes in a signal and modulates a carrier wave to send that signal out. A mixer takes the signal and modifies it according to the type of transmission being done. AM means amplitude modulation. The signal determines the intensity of the transmitter signal. FM means frequency modulation. The transmitters frequency is changed by the incoming signal.There are several ways of sending a signal. Side band and other methods you can read about.
What antenna for 5 watt and 100 what ham radio?
The dimensions of the antenna completely depend on the frequency band in which youplan to operate the radio. This is all covered in the study materials for the license exam.You do have a license to operate that transmitter, don't you ? ! ?

What is FM frequency?
A: This term refers to the FM band or frequency range.
What would cause FM band to fail in radio?
u might have blowed the transmitter
What ii the importance of frequency in radio wave?
In order to separate the signals from separate radio transmitters, different frequencies are used. A receiver filters out a narrow band of frequencies to select the signal from the wanted transmitter and reject the signals from all other transmitters.
