An arbitrary signal m (t) has zero average value and it is bandlimited to 3.2 kHz. It is sampled at the rate of 8 K samples/S. The samples are passed through an ideal bandpass filter with centre frequency of 32 kHz and bandwidth of 6.4 kHz. The output of band pass filter is
AM-DSB signal with suppressed carrier
AM-DSB signal with carrier
AM-SSB signal with carrier
a sequence of exponentially decaying sine waves

3.2*8 = 25.6 khz. So it is the total signal sample passing.

Through in a sec. and we have been given that the total bandwidth of B.P.F is 6.4 with 32 khz carrier frequency.

So 32-25.6 = 6.4 so nothing is suppressed.
