    How to generate a digital sine wave in matlab?

    generate a sine wave in matlab A*(2^10-1) seems be differential output, but there is zero in it. In ideal differential output of 10bit digitizer, there should be no zero. How to get ideal single-end or differential output? Please give details. Thanks very much.

    MATLAB program for SFDR

    adc snr sndr sinad hspice thanks! A question: why span=max(round(numpt/200),5)? why choose numpt/200? if numpt is very large and fundamental frequency is very low, the next power calculate will be wrong

    How to generate a digital sine wave in matlab?

    generate sine wave matlab thanks for your help! But I have a question: A is [-1,1], so A*2^9 is [-2^9, 2^9], in other words, is [0, 2^10]. Actually, the 10bit digitizer can only be [0, 2^10-1]. How to do with overflow value? If I just discard them or replace them by 2^10-1, can it introduce...
