principle of radio communication
A radio transmitter whose job it is to move electric charges rhythmically up and down its antenna sets the signal that is to be propagated in motion. These waves that are propagated carry signals that are received by antennae on your radio or television set. (note: antennas are used both to transmit or and receive signals).

Learning (COL), Vancouver, Canada, to promote the meaningful, relevant and appropriate use of ICTs to serve the educational and training.
coil widely used in radio. • Ernst Alexanderson—born in Sweden, this remarkable inventor developed the first alternator to make transmission of speech (as opposed to the dots and dashes of telegraphs) possible. It is said that this holder of 344 patents “virtually invented everything General Electric did in the field of AM, FM,

of the ionosphere or the processes of radio transmission; see explanation of graphs in Secs. III and IV. Noise Conditions at Receiving Station-- Since radio waves decrease in intensity as they spread out from the transmitter, and since they lose energy by absorption in either the ground or the ionosphere, they finally become.

24. 2 Basic Principles in Radiowave Propagation. 2.2 Transmission Media. As shown in Fig. 2.1, transmission media of radiowaves include all routes between radio transmitter and receiver consisting of one or more of the following main paths: • Free space. • Earth atmosphere. • Ground surface and surrounding medium.

the man who is interested in radio communication, no matter how remotely — he hears about it and sees references to it daily — it is literally thrust upon him from every side. Because of its compara- tively recent entrance into the communication picture, only a rela- tively few books about f.m. have appeared, and these have
