Refer to the file 2015 Sampling lab data Figs post screenshot a2013_03 22 lab dat27 Assume that the screenshot has the horizontal scale 35 ns/div; apply Nyqvist\'s theorem and choose the minimal adequate sampling rate from the list below O 0.5 GSa/s O 0.1 GSa/s O 0.2 GSa/s O 1.0 GSas 2.0 GSa/s

Solution

The signal max frequency is:

=1/35ns=28.57Mhz

the sampling freq>2*message signal

freq>=2*28.57Mhz=57.143Mhz=0.0557143 MHz

so we choose the 0.1G sam/sec is adequeate
