Computer Engineering
Problem 1
Consider the following modulation system
and
for
where
The channel is ideal with Gaussian noise which is
for all
,
wide sense stationary with
for all
.
Consider the following receiver structure
a) Find the optimum value of the threshold for the
system (
e.g. ,
that minimizes the
).
Assume that
b) Find the error probability when this threshold is used.
Problem 2
Consider a PAM system where symbols
,
,
,
are transmitted where
.
The transmitted signal is
where
is a rectangular pulse of duration
and height of 1. Assume that
we have a channel with impulse response
which is a rectangular pulse of duration
and height 1, with white
Gaussian noise with
for all
.
a) Draw a typical sample path (realization) of
and of the received signal
(do not forget to add a bit of noise!)
b) Assume that the receiver knows
.
Design a matched filter for this transmission system.
c) Draw a typical sample path of
,
the output of the matched filter (do not forget to add a bit ofnoise!)
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
_Adnan
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
