52. In the figure, M(f) is the Fourier transform of the message signal .m(t) where A = 100 Hz and    B = 40 Hz. Given $v(t)=\cos(2\pi f_c t)$ and $w(t)=\cos(2\pi(f_c+A)t)$ , where fC>A The cutoff  frequencies of both the filters are fC

The bandwidth of the signal at the output of the modulator (in Hz) is _____.
