A modulating signal $\displaystyle 2 \sin \left(6.28 \times 10^6\right) t$ is added to the carrier signal $\displaystyle 4 \sin \left(12.56 \times 10^9\right) t$ for amplitude modulation. The combined signal is passed through a non-linear square law device. The output is then passed through a band pass filter. The bandwidth of the output signal of band pass filter will be \_\_\_\_ MHz .
