We know that the equation of modulation index for frequency is: μ=Δf/fmμ=Δf/fm Placing the values in the formula, we get: μ=75/15μ=75/15 or: μ=5μ=5 Thus, the frequency modulation index of our station is 5. If you want to learn more about the role of modulation in ot...

It is instructive to study the modulation of one sinusoid by another. In this section, we will look at sinusoidal Amplitude Modulation (AM). The general AM formula is given by where are parameters of the sinusoidal carrier wave, is called the modulation index (or AM index), and is th...
In a digitally advanced era, wires are no longer a requirement to stay in touch. Messages, information, and signals can travel all over the world in seconds. Modulation plays an essential role in communication systems. Below are some of the reasons why modulation is a crucial requirement in c...
Level reduction in a six-level inverter at low modulation indices: (a) SH-PWM, m = 6, ma = 0.5 and (b) SH-PWM, m = 6, ma = 0.15. The minimum modulation index mamin for which a multilevel inverter controlled with SH-PWM makes use of all of its levels, m, is (17.9)mamin=...
6A–C. Under a forward bias, a current flows through the junction, and the intrinsic zone (in green) is flooded with carriers (electrons and holes). A proper overlap between this zone and the optical mode introduces a change in the refractive index (i.e., phase change). This FCPD ...
