This form of communication is a one-way form of communication that does not involve any feedback or response‚ and noise. (F.N.S.

How the Predator UAV Works Military commanders use tactics and strategy in combat to inflict as much damage on the enemy while trying to risk as few personnel and resources as possible. This principle was at the heart of the development of the RQ-1 and MQ-1Predator Unmanned Aerial Vehicle. These high-tech aircraft‚ controlled by a crew miles away from the dangers of combat‚ are capable of reconnaissance‚ combat and support roles in the hairiest of battles. In a worst-case scenario‚ if a Predator

CIRCUIT IDEAS REMOTE-CONTROLLED FAN REGULATOR Dr C.H. VITHALANI sing this circuit‚ you can change the speed of the fan from your couch or bed. Infrared receiver module TSOP1738 is used to receive the infrared signal transmitted by remote control. The circuit is powered by regulated 9V. The AC mains is stepped down by transformer X1 to deliver a secondary output of 12V-0-12V. The transformer output is rectified by full-wave rectifier comprising diodes D1 and D2‚ filtered by capacitor C9 and regulated

I NTRODUCTION It has been known that use of multiple antennas at transmitter and receiver increases speed of data transmission between communication terminals. However‚ MIMO channel capacity is degraded by correlation and keyhole effects. Because of the keyhole effect [1]‚ [2]‚ the rank of MIMO channel matrix is reduced to

Presently in the twenty-first centaury wireless networking is gaining because of speed and ease of deployment and relatively high network robustness. Modern era of optical communication originated with the invention of LASER in 1958 and fabrication of low-loss optical fiber in 1970. When we hear of

chapter 3 Amplitude Modulation Fundamentals n the modulation process‚ the baseband voice‚ video‚ or digital signal modifies another‚ higher-frequency signal called the carrier‚ which is usually a sine wave. A sine wave carrier can be modified by the intelligence signal through amplitude modulation‚ frequency modulation‚ or phase modulation. The focus of this chapter is amplitude modulation (AM).
