InterviewSolution

1.	A signal () with bandwidth 500 Hz is first multiplied by a signal () 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
Answer» 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).
