As of now, there are numerous modulation schemes. The amplitude, frequency, and phase of each modulation scheme differ. The transmission's bandwidth must be determined in order to choose the best transmission method where the bits travel at 280 kbps rate. Hint: Pick the option that doesn't consume too much bandwidth and closer to your calculated output a) Choose the best modulation scheme for sending up to 260 KHz • Binary Frequency shift keying (BFSK) • Quadrature Phase shift Keying (QPSK) • Quadrature amplitude modulation (QAM) • None Answer: ◆ b) Choose the modulation scheme for sending up to 512 KHz • Binary Frequency shift keying (BFSK) • Quadrature Phase shift Keying (QPSK) • Quadrature Amplitude modulation (QAM)
