I was introduced to this book in comp.dsp so i assumed there r ppl here
who are familiar with this book.

I have a question from this book. It is from Chapter2: Periodic
Sampling section2.3 Bandpass sampling, equation 2-10:

(2Fc-B)/m >= Fs >= (2Fc+B)/(m+1)

What is this 'm'? I can't find its definition, can someone tell me
where can i find it in the book or tell me its definition?

Thx guys...

m is the number of spectral replications between DC and the band being
sampled. See Eq. 2.6 and the paragraph just preceding it. Maybe Rick
will make that stand out more in his nest revision.
