To my knowledge both are familiar but Delta-Sigma seems more matched to the functional description of the convertor (make a difference and then average for spectral...
HelloThe sinc(x)=sin(x)/x goes to 1 when x goes to 0... sin(x) and x both goes to 0 but the ratio does not. When x is small sin(x) is equivalent to x-x³/6 so the...
I don't know this book either...But the figure is indeed confusingThe Sinc function (of m) should peak at m=k, as it does, because the cosine has k periods in the...

Hello..As I see it:A Doppler shifted signal is a time compressed version of the original signal: if S(t) is emitted S(at) is received, where a=1-v/c approximately.Now...
