C. Modulation Index Effect on Level Utilization For low amplitude modulation indices, a multilevel inverter will not make use of all of its levels and at very low modulation indices it operates as if it is a traditional two-level inverter. Figure 17.19 shows two simulation results of what the...

Design Advice for Modulated Signals Today, you don’t really get to choose between amplitude modulation vs. frequency modulation in a communications system. Whether you’re operating in a licensed or unlicensed band, the type of modulation you use will depend on the wireless standard or signal...
Amplitude modulation (AM) is a process by which the wave signal is transmitted by modulating the amplitude of the signal. Learn about amplitude modulation in detail here.
