A signal m(t) with bandwidth 500 Hz is first multiplied by a signal g(t) where 
. The resulting signal is then passes through an ideal low pass filter with bandwidth 1 kHz the output of the low pass filter would be
. The resulting signal is then passes through an ideal low pass filter with bandwidth 1 kHz the output of the low pass filter would beAnswer: Option
Explanation:
Multiplication in time domain is equivalent to convolution. According to the property of impulse signal, convolution of a signal m(t) with δ(t) is signal itself.
m(t) x g(t)
m(t).
