Experiments Included:

  • Understanding of IT-4101
  • AM DSB Modulation
  • AM SSB-SC Modulation
  • AM DSB-SC Modulation
  • Transmission of AM DSB-SC Modulated

IT-4101 is the comprehensive training system designed to analyze the DSB/SSB techniques used for Amplitude Modulation. The trainer consists of signal generator and Modulator section. It provides the full understanding of conventional Amplitude Modulation circuits. Trainer can transmit modulated signal at certain power level so signal is received by its receiver part.

For wired application 455KHz carrier is used. For transmission 1MHz carrier signal is used.
