must be much larger than the wavelength of the radio waves. The relatively short wavelength of microwaves allows reasonably sized dishes to exhibit the desired highly directional response for both receiving and transmitting. Microwave radio relay is a technology for transmitting digital and analog signals‚ such as long-distance telephone calls‚ television programs‚ and computer data‚ between two locations on a line of sight radio path. In microwave radio relay‚ microwaves are transmitted between the

Then they told me “What do you think the entertainment was before television was invented?” “What was the entertainment before the television was invented?” I asked. I went out to search for more information. I asked my old relatives and searched in the internet about entertainment before the invention of television. I learned that before the invention of television‚ commercial radio broadcasts not only aired music and news as they do

AM with FM edit Pros and Cons of AM vs FM The advantages of AM radio are that it is relatively easy to detect with simple equipment‚ even if the signal is not very strong. The other advantage is that it has a narrower bandwidth than FM‚ and wider coverage compared with FM radio. The major disadvantage of AM is that the signal is affected by electrical storms and other radio frequency interference. Also‚ although the radio transmitters can transmit sound waves of frequency up to 15 kHz‚ most receivers

Amplitude modulation or AM as it is often called‚ is a form of modulation used for radio transmissions for broadcasting and two way radio communication applications. Although one of the earliest used forms of modulation it is still in widespread use today. The first amplitude modulated signal was transmitted in 1901 by a Canadian engineer named Reginald Fessenden. He took a continuous spark transmission and placed a carbon microphone in the antenna lead. The sound waves impacting on the microphone
