    hi everyone,
    need some clarification here:)
    if I m working with 12 bit adc....having sampling rate(50ksps).....so in 60 sec I m suppose to get (50*1000*60*12) =36000000 bits(zeroes or ones)
    Is it true?
    plz help me with it!
    thanxs;
    regards

    Maybe yes, maybe no. it all depends how you process the data.

    If you process it a 12 bit words then yes, you will end up with 36000000 bits of data but you may find it easier to to process each sample as a 2 byte word (16 bits). This would be the case if you were using a high level language to further process the captured data. In that case 60 seconds of data would be 5.7Mbytes or 48000000 bits.

    I think is just a simple school question and the answer is correct.
