is pulse modulated. Pulse-modulated radar can determine the distance to a target by measuring the time required for an extremely short burst of radio-frequency (r-f) energy to travel to the target and return to its source as a reflected echo. Directional antennas are used for transmitting the pulse and receiving the reflected echo‚ thereby allowing determination of the direction or bearing of the target echo. Once time and bearing are measured‚ these targets or echoes are calculated and displayed

Premium Modulation Transistor Control theory
defined as a subset of telecommunication involving the transmission of data to and from computers and components of computer systems. More specifically data communication is transmitted via mediums such as wires‚ coaxial cables‚ fiber optics‚ or radiated electromagnetic waves such as broadcast radio‚ infrared light‚ microwaves‚ and satellites. Data Communications = Movement of computer information by means of electrical or optical transmission systems Information can be represented using analog signals

considered scarce because of the limited number of frequencies for operation and two parties cannot broadcast on the same frequency in the spectrum. Interference not only can be caused by broadcasters but by natural phenomenons like thunderstorms. Another factor‚ which can attribute to interference is one known as Intermodulation. This happens when two or more frequencies affect each other’s transmission. What key decision did Congress make in 1927 in regards to the electromagnetic spectrum? In 1927

finder Introduction The aim for this assignment is to write a program for the ultrasonic range finder. It is similar to the sonar system‚ which emit a time-limited ultrasonic wave and receive the echo of the signal. The delay between transmission and reception of the Signal can be used as a measure for the distance at which the object is found. The process shows below. Overview The microcontroller program needs to implement a ultrasonic range finder. First switch the transceiver to ‘transmitting’

changes in the amplitude or frequency of a radio transmission to convey information. Band Plan A set of decisions regarding how radio spectrum will be used. The band plan for a given block of spectrum typically establishes (1) which services can be offered‚ (2) how the block will be divided both across and within geographical areas‚ and (3) the rules for assigning licenses to use that spectrum to specific parties. Bandwidth The transmission capacity of a communication medium. Carrier Wave
