1 WORK PRINCIPLE OF FM RADIO RECEIVER Competency : Repairing of Radio Receiver

2 Teknologi dan Rekayasa

3 FM Superheterodyne Receiver circuit Teknologi dan Rekayasa

4 RF Amplifier with FET Teknologi dan Rekayasa Sample Image circuit RF Amplifier With Active Components FET

5 RF Amlpifier with MOSFET Teknologi dan Rekayasa WITH RF amplifier MOSFET: A dual gate (double gate) Common Source MOSFET RF amplifiers

6 Limitter Circuit Teknologi dan Rekayasa Discriminator: functions retrieve information from a high frequency carrier Deemphasis: is a series of paired after the detector that functions return a high frequency of the frequency of intelligence (information) back to the amplitude level equal to the low frequency

7 Principle of FM modulasi Teknologi dan Rekayasa FM band of the electromagnetic spectrum lies between 88 MHz and 108 MHz

8 Frekuensi on FM Teknologi dan Rekayasa Changes in large- scale frequency is proportional to the amplitude of the signal information. FM radio carrier around 100 MHz is limited to the modulation of + / - 0.1 MHz

9 Diagram blok FM simple Teknologi dan Rekayasa

10 Modulasi sinyal FM Teknologi dan Rekayasa

11 Band pass filter Teknologi dan Rekayasa

12 THE END Teknologi dan Rekayasa By. Setyo Harmadi,ST SMK Muhammadiyah 3 Yogyakarta
