Is a sampling rate of 160 million samples per second enough?
How do you know what is enough?
now it all depends on what your doing with this
signal ?
are we simply delaying it only or are we examining
the signal also ?
using FFT you need a min of 2 samples to
regenerate the 80 mhz later on.
and also , there is the problem of resolution.
the highest bit Decoder is needed if this
is a complex signal ?
your talking about a lot of expensive components.
