When you press the remote‚ 38 KHz infrared rays (IR) is generated through remote control (which used as transmitter) and these rays are received by TSOP1738 which act as receiver in our circuit. Then these weak signals at output pin 3 of TSOP1738 are amplified by transistorT1. Now‚ these amplified signals are fed into the clock input pin 14 of IC2. Therefore when you press any button on

cryptography are Confidentiality (the information cannot be understandable to anyone except to the intended person)‚ Integrity (the information cannot be altered by third person between transmitter and sender)‚ Non-repudiation (the creator/sender of the information cannot deny at a later stages)‚ Authentication (the sender and receiver can verify each others identity). In todays world‚ right from the internet sites to banks need security. Hence the cryptography systems are playing a vital role. There are different

transmission of digitally encoded analog signals requires significantly more bandwidth than simply transmitting the original analog signal. Analog signal must be converted to digital codes prior to transmission and converted back to analog form at the receiver‚ thus necessitating additional encoding and decoding circuitry. 3. Define data Signalling Rate. Data signalling rate is defined as the rate measured in terms bits per second(b/s) at which data are transmitted. Data signaling rate Rb=I/Tb Where Tb=bit

input power. To fully modulate a 10kW carrier requires 5kW of intelligence. Therefore‚ to provide 5kW of sideband (intelligence) power through a 70% efficient amplifier requires a dc input of: 5kW / 0.70 = 7.14kW 5. A transmitter with a 10kW carrier transmits 11.2kW when modulated with a single sine wave. Calculate the modulation index. If the carrier is simultaneously modulated with another sine wave at 50% modulation‚ calculate the total transmitted power.

Although others had experimented with using a cathode ray tube as a receiver‚ the concept of using one as a transmitter was novel. By the late 1920s‚ when electromechanical television was still being introduced‚ several inventors were already working separately on versions of all-electronic transmitting tubes‚ including Philo Farnsworth and Vladimir

This data will be continuously transmitted to the RF receiver connected to the microcontroller (AT89S52). This GPS will be location the position of vehicle and transmit that data to the microcontroller.

telephone network [1]. 1. INTRODUCTION Radio control (often abbreviated to R/C or simply RC) is the use of radio signals to remotely control device. The term is used frequently to refer to the control of model vehicles from a handheld radio transmitter. Industrial‚ military‚ and scientific research organizations make use of radio-controlled vehicles as well. A remote control vehicle (RCV) is defined as any mobile device that is controlled by a means that does not restrict its motion with an origin
