Question from Understand DSP by Richard Lyons

Started by Ant_Magma December 22, 2005
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.
