Given Vmax=5.22VV_{max}=5.22V and Vmin=1.33V,V_{min}=1.33V, modulation(m) is given by,

m=((VmaxVmin)/(Vmax+Vmin))m=((V_{max}-V_{min})/(V_{max}+V_{min}))

m=(5.221.33)/(5.22+1.33)m=(5.22-1.33)/(5.22+1.33)

m=3.89/6.55=0.5939(4 decimal places)m=3.89/6.55=0.5939(4\displaystyle\space decimal\displaystyle\space places)

Therefore, percentage of modulation is given as,

percentage of modulation=m100=0.5939100=59.39%percentage\displaystyle\space of\displaystyle\space modulation=m*100=0.5939*100=59.39\%
