    Signal to Distortion Ratio (SDR) for a sinewave (assuming uniform sinewave and distortion) is given by 3/2 (2^(2B) = x
    where B is the no of bits
    dB SDR = 10log(x)

    Rule of thumb
    ***** One bit added adds 6dB*********

    3/2 (2^(2B)>>>>> add one bit then 3/2 (2^(2(B+1))= x* 4

    10 log 4 = 6 dB

    Everything above is based on rounding (quantization).
