A modulated wave s(t) = [1 + m(t)] cos(2π 106 t) is applied to the system shown
m(t) is bandlimited to 1 kHz and |m(t)| < 1 the low pass filter is ideal with pass band magnitude of 1 and cut off frequency of 3 KHz the output Y(t) is equal to.
1
\(\left( \dfrac{1}{\sqrt 2} \right) [ 1 + m(t)]\)
2
[1+ m(t)]
3
m(t)
4
√2 [1 + 2 m(t)]
