A telecommunications company is designing a system to transmit digital TV signals over a long distance. They need to choose a modulation technique that can carry multiple bits of data in each symbol to maximize data rate. Which modulation technique might be suitable for this?

  • ASK (Amplitude-Shift Keying)
  • BPSK (Binary Phase-Shift Keying)
  • FSK (Frequency-Shift Keying)
  • QAM (Quadrature Amplitude Modulation)
QAM is suitable for maximizing data rate by encoding multiple bits per symbol. It combines both amplitude and phase modulation, allowing for higher data throughput.
