RADIO TRANSMITTER AND RECEIVER
TRANSMITTER
(TX)
In electronics and telecommunications a radio transmitter is an electronic device which, with the aid of an antenna, produces radio waves. The transmitter
itself generates a radio frequency alternating current, which is applied to the antenna. When excited
by this alternating current, the antenna radiates radio waves.The term transmitter is usually limited to
equipment that generates radio waves for communication purposes; or radio location, such as radar and navigational
transmitters.A transmitter can be a separate piece of electronic equipment, or
an electrical circuit within another electronic device. A transmitter and receiver combined in one unit is
called a transceiver.
The term transmitter is often abbreviated "XMTR" or
"TX" in technical documents. The purpose of most transmitters is radio communication of information over a
distance.The information is provided to the transmitter in the form of an
electronic signal, such as an audio (sound) signal from a microphone, a video (TV) signal from a TV
camera, or in wireless networking devices a digital signal from a computer. The
transmitter combines the information signal to be carried with the radio
frequency signal which generates the radio waves, which is often called the carrier. This process is
called modulation.
A radio transmitter is an electronic circuit which transforms electric
power from a battery or electrical mains into a radio frequency alternating current, which reverses direction millions to billions
of times per second. The energy in such a rapidly-reversing current can radiate
off a conductor (the antenna) as electromagnetic waves (radio waves).
RECEIVER (RX)
A radio receiver is an electronic circuit that receives its
input from an antenna, uses electronic filters to separate a wanted radio signal from all other signals picked up
by this antenna, amplifies it to a level suitable for further processing, and finally
converts through demodulation and decoding the signal into a form usable for the consumer, such as sound,
pictures, digital data, measurement values, navigational positions, etc.Demodulation is the act of extracting the
original information-bearing signal from a modulated carrier wave. A demodulator is an electronic circuit that is
used to recover the information content from the modulated carrier wave.
The receiver in information theory is the receiving end of a communication channel. It
receives decoded messages/information from the sender, who first encoded them. Sometimes the receiver
is modeled so as to include the decoder. Real-world receivers like radio receivers cannot be expected to
receive as much information as predicted by the noisy channel coding
theorem.
HKT6A
TRANSMITTER
HKT6A transmitter is
used is 6 channel, FM modulating with a 2.4 GHz frequency band, the frequency
at which it transmits the modulated signal. the signal transmitted by the
transmitter is received by a HKT6A receiver which DE-modulates the signal to
get the original signal.
