Remote Control System

About Remote Control 

Hi friends In present time almost all the people familiar from remote it's use in many things like television, toy cars and etc. Here we discuss about remote control, its function and how is it work and many more.

 Remote Control base on transmission system we know that all transmission possible by two two parts. 

1:Transmitter (The part which transmit the signal) 

2:Receiver (It receives the signal from transmitter) 

#

Our Remote Control system behave as Transmitter and the other objects like television behave as receiver.

In Remote Control system mainly Infrared (IR) spectrum are use for transmit the signal
some years ago ultrasonic tone are the use for transmit the signal. The signal are transmit in the form of pulse. For generate the (IR) of spectrum pulse a Light Emitter Diode of (LED)  are use in the front of the Remote. In case of Remote Control system each button has unique pluse code which is transmit through LED when we press any button of the Remote Control. These pluse code are receive by the receiver and respond for those pulse.
These pulses are exchanging as messages within the computing system by the protocol.

Protocol :

Protocols are  use to exchange the message within the computing system as required for the different parts of the system. In other words it work  as interface within the computing system part. ex (RC-5) 

Transmitter :

The main function of the transmitter are transmit the signal there are different way of transmit the signals but generally the transmit signals (Those signals you want to transmit) are transmit through  the carrier wave by the modulation on carrier wave after the modulation signals are transmit. 

Receiver :

Receiver are use to receive the transmit signals by the demodulation (filtration of the transmit signals)  of the the transmit signals after the filtration of the the signals  receiver receive the desired signals and avoid the other.
