This message signal will be referred to as m1(t) in most of the remaining problemson this test: m_{1}(t)=\cos ^{2}\left(2 \pi 8000 t+\frac{\pi}{8}\right) Find B1, the bandwidth of m1(t). Find P1,

the power of the m1(t). . Find m(t), the derivative of m1(t). - Find mp1, the peak value of m1(t). e. Find m,, the peak value of the derivative of m1(t).'p'
