How is the data put on radio waves?

Hi all..to make my blog updated, since i am quit busy with my study schedules, i have tried to copy some informative page for visitors eyes regarding how is the data travel through waves. Maybe a lot of us still do not know how the data that we send everyday (voice, cw) work with waves including me until i found this article.
There are two common ways to put information in a radio wave, and you've likely run into them yourself. They are called A.M. and F.M. just like the two choices you've always known are on a radio. To understand these two ways of sending information it is important to know that radio waves, by themselves, have very regular patterns. Generally they keep the same amplitude or frequency all the time. (Amplitude is the "height" of the radio wave, frequency is how close the waves are to each other.)






A.M. stands for amplitude modulation. In this method, the information is put into a radio wave by varying the amplitude. For example, if all we wanted to do was send 1's and 0's, we could have just two different levels of amplitude that correspond to these numbers--1 being high, 0 being low.



F.M. stands for frequency modulation. This time the amplitude is kept constant, it is the frequency that is varied..



So ladies and gentleman, see how beauty and brilliants the creator up there..Think about it..Until then, see u in next post..73

Cerita Ghairah: Liana Memalukan Keluarga

"Sungguh memalukan!!"

"Maafkan saya bapak, sa..saya..saya menyesal!", Liana terisak-isak di hadapan bapaknya.

"Menyesal ? Dah terlambat! Kau tahu tak? Nama keluarga kita dah tercemar! … belum pernah keturunan kita kena macam nie? Kau tahu tak!" herdik bapak Liana.

"Sudahlah bang", mak Liana menyampok, "Kita bincangkan sekeluarga."

"Nak bincang aper lagi? … anak awak nie dah mengaku… … issshhh… … ." balas bapanya sambil memalingkan mukanya ke arah pokok di luar.

Liana betul betul menyesal dgn pengakuannya itu… kalau dia tahu bapaknya jadi camnie dia diam je… toksah mengaku lagi baik. Seluruh hidupnya seakan-akan runtuh di depan matanya, masa depan dia gelap? … dia telah mencemarkan nama baik keluarga dan keturunannya. Dia tahu masyarakatnya tidak akan dapat menerima dia lagi. Dia tahu keluarganya dah kecewa. What a letdown?

Di satu pagi yg hening dia keluar berjalan ke arah satu bangunan pencakar langit yg tinggi. Perlahan-lahan dia menaiki tangga sampai ke atas bumbung bangunan itu. Dia memandang ke bawah… dia lihat kereta dan org ramai bersepah kat bawah macam semut-semut yg baru kena spray dgn Baygon.

Liana dah nekad apa terjadi… . jadilah… .. Dia dah memalukan keluarganya, dia mencemarkan keturunannya, bapanya tidak mahu menerima atas kelemahannya itu.

Liana tebayangkan wajah maknya, air matanya menitis. Emaknya lah tempat dia bermanja, emaknya la yg akan meyelimutkan dikala sejuk, menyuapkan dikala lapar, wajah adik-beradik kembarnya juga terbayang dimata.

Sambil mengesat airmatanya, dia menarik nafas panjang… berjalan kehadapan hingga ke hujung bangunan itu. Setapak demi setapak dia melangkah ke hadapan hingga dirinya terjatuh melayang ke bawah… dia dapat rasakan angin yg begitu deras memukul mukanya… jantungnya berdegup pantas bila dia melihat bumi semakin dekat… .. dgn satu tarikan nafas yg dalam, Liana mengembangkan sayapnya, SWOOOOOSSSSHHHHHHHHH!!!… … .. dia terbang .

"Yessss! Yessss! Yessssssssssssssss! I’ve made it!!!!!", dia memekik keriangan.

Finally dia dapat melawan fobianya… dia dah no longer afraid of height… sebagai seekor burung, itulah yg sepatutnya menjadi fitrah semulajadi… selama ini dia takut… .. ye dia takut pada tempat tinggi dan kerana ketakutan inilah membuatnya tidak mahu terbang… dah bertahun dia rahsiakan hal ini dari keluarganya… . Sebab tu bapak dia kecewa bila dia membuat pengakuan itu kerana memang tak pernah seumur hidup seekor burung takut pada ketinggian.

Tapi sekarang dia dah tak takut, dia dah berani… . dia dah boleh terbang…

Friendship

Hi all..So long not to update my blog with my own word. Usually to make my blog update i use to copy any informative page from any other website for visitors eyes. However i do believe that those friends who ever visit here perhaps may get something from my post. Today i would like to write about friendship. The word that i really appreciate it when i realized how beauty the world is. Friendship isn't always easily described. The Eskimos, they say, have a hundred different words for snow. Unfortunately, the English language isn't quite as innovative, though it has vast opportunities to differentiate meaning. Certainly, Love is one of those opportunities. And so, too, is Friendship.

Instead of different words, however, we're stuck with simple adjectives. Close friend. Best friend. Childhood friend. Intimate friend. Trusted friend. Beloved friend. But whether you use adjectives or different words, few could deny the nearly infinite meaning in such a simple word.

Friends are special people. We can't pick our family, and we're sorely limited in the number of them at any rate. Society and mores (and often our own conscience) dictate we select a single mate. But our friends can be as diverse and infinite as the adjectives we choose. Our friends, in a very real sense, reflect the choices we make in life. So since we get involve in amateur radio as a hobby, of course we meet a lot of friends. Therefore, appreciate them as we appreciate our self. Until then..73
