1 Leure 3: FM Transmiers & Reeivers Review of Previous Leures Frequeny Modulaion FM Transmier FM Demodulaion Tehniques FM Reeiver Conlusions & Disussions Leure Noes are available from: hp://homepages.unl.a.uk/~aghizas
2 Review of Previous Leures WHAT is Modulaion and WHY we Modulae? Modulaion is a PROCESS by whih he properies of one signal is made o vary he properies of anoher signal! Signals are variaion of Elerial Curren or Volages over ime. Signals have basially THREE basi properies Ampliude Phase Frequeny
3 A Typial Signal: A Sinusoidal Signal x( Asin( A: Is he Ampliude : Is he Phase in Radians : Is he Frequeny in Radians = 2 f f is he Frequeny in Hz
4 Transmier Why Modulaion? Communiaion Channel Reeiver
5 Cond Speeh => 300Hz Wavelengh C f Km Size of he Transmier Anenna: L Km 10
6 Cond Reduion in he Size of Anenna Muli-Signal Transmission over he same hannel Less effeed by Noise
7 How To Inrease The Frequeny? We Sele a known signal (e.g. Sinusoidal and KAKE i TO CARRY he SPEECH signal! How? This is wha we all Modulaion. We Can Make he Ampliude of he Sinusoid To arry i Ampliude Modulaion We Can Make he Frequeny of he Sinusoid To arry i Frequeny Modulaion We Can Make he Phase of he Sinusoid To arry i > Phase Modulaion

11 FM Demodulaion Modulaion ours in he TRANSMITTER Saion. We have so far managed o CONVERT our MESSAGE signal, m( ino a suiable form for ransmission. Wha is remaining is o design he Reeiver. This is alled he Demodulaion Proess. Demodulaion is he proess ha happens in our RADIOS i.e. he RECEIVER.

19 Conlusions & Some Observaions The proess of Modulaion hanges he properies of one signal wih respe o anoher signal. Two Examples of Modulaion proess is AM & FM. AM & FM are boh very simple o Realize AM is more SENSITIVE o noise and inerferenes han FM FM uses 88 MHz o 108MHz band, AM uses 300KHz o 3MHz.
