Frequency Modulation & Demodulation [FM] Trainer

The single board trainer with inbuilt I.C regulated power supply helps to construct Modulator & to demonstrate how Signal can be added to a carrier & observe the frequency Modulated waveform & measure the frequency deviation.

The demodulation part helps to demonstrate how Signal can be recovered from a frequency modulated carrier by using PLL Demodulator.

The trainer consists of :

    1. Modulator using XR2206 with Carrier Wave Generator [45 KHz].
    2. Demodulator using I.C 565.
    3. Signal Frequency Generator :
      • Variable Frequency : 100 Hz – 1 KHz
      • Amplitude : 4.6 Vpp (max)

Additional Accessory Required :

  • Dual trace oscilloscope
