Fm station are tuned at its carrier frequency. Kung makikita mo sa oscilloscope at specturm analyzer mas maiintindihan mo ang concept nito.

Tama yun. Ang center carries f ay yung mismong f nya sa dial mo. It swings within a bandwidth, + and - something. Sa AM ang signal strength ang nagbabago in conformity with the info send, thus amplitude modulation. Ung amplitude and binabago. Kaya and cirkit nito ay sa dulo, sa final output niya binavary and lakas by way of running the B+ sa secondary ng audio out trransistor. Sa fm, binvary and freq. and this is done sa oscillator stage ang transmitter.GAmit usually as varicap, variable capacitor. Voltage to capacitance change siya, kaya nagbabago ang frequency.

Hope I helped.

97.1 Mhz din po. carier frequency kasi, ito yung nag dadala ng audio frequency para mapakinggan sa mga fm radio reciever. mula po sa modulator ng transmiter mag m-mix ang AF sasakay sa carier frequency. yung carier frequency ang siyang nag sisilbing sakayan ng AF signal.
