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

• A. AM-DSB signal with suppressed carrier
• B. AM-DSB signal with carrier
• C. AM-SSB signal with carrier
• D. a sequence of exponentially decaying sine waves
