wireless communication represents

One desirable feature of radio transmission is that it should be carried without wires (i.e.,) radiated into space. At audio frequencies, radiation is not practicable because the efficiency of radiation is poor. However, efficient radiation of electrical energy is possible at high frequencies (>..

Basic Principles of Wireless Radio Communication - Let us now discuss the basic principles of wireless radio communications. We shall mainly concentrate on the principle of amplitude modulation and demodulation. The simplest scheme of wireless ..

. So, the signal power progressively decreases with increasing distance. The receiver operates on the output signal from the channel in preparation for delivery to the transducer at the destination. Receiver operations include amplification to compensate for transmission loss. These also include de..

The circle graph represents the expenditures of a software company in one year. How much did the company spend on communication? => $20 million or $25 million or $10 million or $15 million..

A school enrolls students based on their performance in the written test and communication skill test. Each test has a maximum score of 75. The graph shows the inequalities that tells the status of a candidate: For admission x + y ≥ 50 For scholarship 4 x + 5 y ≥ 300 For accommodati..

Poet communicates an experience. The poet's communication is received by our senses. The senses consist of seeing, hearing, smelling, feeling and touching. The poet has to create an image to stimulate any of these senses. This is called imagery. It can be defined as the represe..

Golgi complex is represented by several structures like membranes, vesicles and granules. It appears as a central stack of flattened inter communicating sacs called cisternae in a parallel arrangement along with tubules and vesicles. The cisternae are continuously being formed a..

When a modem first makes a connection, you will hear screeching sounds coming from the modem. These are digital signals coming from the computer to which you are connecting being modulated into audible sounds. The modem sends a higher-pitched tone to represent the digit 1 and a lower-pitc..

How Modems Work? - When a modem first makes a connection, you will hear screeching sounds coming from the modem. These are digital signals coming from the computer to which you are connecting being modulated into audible sounds. The modem sends a higher-pitched tone to represent the digit..
