You will work through an example problem that explores the effects of sample-rate compression and expansion on the spectrum of a signal.
Multirate theory exercise
Consider a sampled signal with the DTFT
shown in
[link] .
Assuming
, use the relations between the DTFT of a signal
before and after sample-rate compression and expansion(
[link] and
[link] ) to sketch
the DTFT response of the signal as it passes through themultirate system of
[link] (without any
filtering). Include both the intermediate response
and the final response
. It is important to be aware that the translation
from digital frequency
to analog frequency depends on the sampling rate.
Therefore, the conversion is different for

advantage of electronic microscope is easily and clearly while disadvantage is dangerous because its electronic. advantage of light microscope is savely and naturally by sun while disadvantage is not easily,means its not sharp and not clear

A scanning electron microscope (SEM) is ideal for situations requiring high-resolution imaging of surfaces. It is commonly used in materials science, biology, and geology to examine the topography and composition of samples at a nanoscale level. SEM is particularly useful for studying fine details,
