Question
For an amplitude modulated wave, the maximum amplitude is found to be $9 \mathrm{~V}$ while the minimum amplitude is found to be $3 \mathrm{~V}$. The modulation index is(A) $100 \%$(B) $75 \%$(C) $50 \%$(D) $25 \%$
Step 1
Step 1: The modulation index for an amplitude modulated wave is given by the formula: \[ m = \frac{A_{max} - A_{min}}{A_{max} + A_{min}} \] where \(A_{max}\) is the maximum amplitude and \(A_{min}\) is the minimum amplitude. Show more…
