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] .
DTFT of the input signal.
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
and

Bacteria doesn't produce energy they are dependent upon their substrate in case of lack of nutrients they are able to make spores which helps them to sustain in harsh environments

But not all bacteria make spores, l mean Eukaryotic cells have Mitochondria which acts as powerhouse for them, since bacteria don't have it, what is the substitution for it?
Assimilatory nitrate reduction is a process that occurs in some microorganisms, such as bacteria and archaea, in which nitrate (NO3-) is reduced to nitrite (NO2-), and then further reduced to ammonia (NH3).
Elkana
This process is called assimilatory nitrate reduction because the nitrogen that is produced is incorporated in the cells of microorganisms where it can be used in the synthesis of amino acids and other nitrogen products
There are nothing like emergency disease but there are some common medical emergency which can occur simultaneously like Bleeding,heart attack,Breathing difficulties,severe pain heart stock.Hope you will get my point .Have a nice day ❣️

define infection ,prevention and control
Innocent
I think infection prevention and control is the avoidance of all things we do that gives out break of infections and promotion of health practices that promote life
