Frequency (UHF) 300MHz-3GHz Super High Frequency (SHF) 3GHz-30GHz 7 A microwave transmitter typically requires a +8dBm level to drive an input fully. What is the actual voltage measured if +10dBm? Assume 600 ohm system. (2.45 V) = 10 9 Convert powers to dBM equivalents. = -10 dBM 15. Define electrical noise? Any undesired voltages or currents that ultimately end up appearing in the receiver output often called static. 16. Describe external and internal noise? External

experienced by a receiver in a flat fading channel. These techniques can be employed at both base station and mobile receivers. Spatial Diversity is the most widely used diversity technique. In this technique multiple antennas are strategically spaced and connected to common receiving system. While one antenna sees a signal null‚ one of the other antennas may see a signal peak‚ and the receiver is able to select the antenna with the best signal at any time. The CDMA systems use Rake receivers which provide

or feeling to a receiver. The process of communication is composed of three elements: one is the source like speaker‚ transmitter‚ or instructor. Second is the symbols used in writing and transmitting the message such as words and signs. And third is the receiver like listener‚ reader‚ or students‚ although the receiver does not need to be present or aware of the sender ’s intent to communicate at the time of communication. The communication process is completed once the receiver has understood

Radio-controlled car Radio-controlled (or R/C) cars are usually categorized as either "toy" or "hobby" grade. Remote control vehicles are usually of one of two types: control of a vehicle by radio transmission or by a wire connecting between the transmitter and car. This article focuses on the radio-controlled vehicle category‚ both toy and hobby grades.Cars are powered by various sources. Electric cars are powered by small but powerful electric motors and rechargeable nickel-cadmium‚ nickel metal

CHAPTER I INTRODUCTION Most mains-operated equipment in use today is connected to the supply via plugs and sockets. These are generally acceptable in benign environments‚ but can be unsafe or have limited life in the presence of moisture. In explosive atmospheres and in undersea applications‚ special connectors must be used. This paper describes a technique‚ the contactless energy transfer system (CETS)‚ by which electrical energy may be transmitted‚ without electrical connection or physical

Photodiode receivers or CCD/CMOS sensors can be used (typically found in digital cameras). 4 WORKING Resonant Cavity LED is being used for transmission purpose. This will allow modulation at very high frequencies. Receivers may include CMOS or CCD (Charge Coupled Device) sensors. To prevent interference between bit streams‚ modulation
