A message signal of frequency 5 kHz is used to modulate a carrier signal of frequency 2 MHz. The bandwidth for amplitude modulation is :

Match List I with List II

Choose the correct answer from the options given below :

A modulating signal is a square wave, as shown in the figure.

If the carrier wave is given as $$\mathrm{c(t) = 2\sin(8\pi t)}$$ volts, the modulation index is :

Find the modulation index of an AM wave having $$8 \mathrm{~V}$$ variation where maximum amplitude of the AM wave is $$9 \mathrm{~V}$$.
