In the previous topic, we have discussed about the magnitude that is, you know, next in the middle
of year's selection criteria, we are going to discuss the maximum RF and the power to the receiver,
as we have discussed previously in a case of a software defined radio system.
We have a transmitter, we have receiver, or we have only a transmitter board and we can have only
a receiver or so any kind of as you are.
Can we talk like this?
Moreover, we have discussed earlier we we can do now or we can control the transmitter power of the
transmitter using up what amplifiers we can increase the power of transmitter.
Similarly, in the case of receiver, suppose I am transmitting a 20 year DBM signal power.
So my mission, my transmission and its signal power is 20 degrees.
So I am transmitting through Dysport and I want to receive this signal to my receiver.
In this case, according to the manufacturer, the provider dataset, how much power can we provide
to our this?
But suppose we can provide only minus 10 DVM of power to this receiver.
But I want to receive 20 DB more power than what I can do.
I have to use the Internet.
What does nature do?
So the originators reduce the power of the signal.
It can reduce the signal strength.
So we can suppose we can use the attributes so that for example, I want to give 20 devia and I want
here minus 20.
So what I have to do, I have to do you I have to use a 30 D.V. at UNITAID.
So that.
Twenty minus 30 degrees.
I can get to minus 10.
DVM.
Of power here.
So using a generator, you can reduce the received power, whatever that is you want to avoid by the
severe damage.
I suppose the second scenario, maybe I have a transmitter, I am transmitting signal from here and
my receiver can give all of away so that I have transmitted the signal in between.
I have to use the repeaters to increase the signal strength and the receiver say I have to ensure that
it should not get damaged.
So I have not to cross that maximum threshold level of power which a receiver can access.
So in the case of receiver, there are low noise amplifiers or automatic gain control systems are already
available in that receiver, but they can control the power to a certain level.
Beyond that, they they cannot handle such putting so much power.
Therefore, the prime criteria to receive a signal and the receiver of software defined radio, it should
be that we have not crossed the threshold limit of the receiver power.
Otherwise it's a burden to them is therefore in this cockpit.
We have discussed about the maximum out of power to the receiver and we have seen that we have to restrict
ourselves to a certain limit, as mentioned by the manufacturer, that, as you know, in summary,
we have in this module, we have discussed the different as the selection criteria, for example, frequency
bandwidth sampling.
It makes it of input to receiver error, the magnitude cost efficiency, tradeoff and dynamic.
So we have once we want to purchase of creative find a solution or a system, we have to keep all these
parameters in the mind so that we can choose a software defined radio according to our need, and we
do not pay much higher for the load requirements of the you.
In fact, you can start with as much as possible of 150 dollars a year or more later.
Then, for example, our deal is to add you can go beyond the dealers twenty, thirty dollars that you
can use.
So depending on the requirements you have to select to go on to twenty dollars a year, thirty dollars
a year or even to use a higher, much higher requirement of Asgeir.
So this module will definitely help you to understand and select the rule of law as diverse as the selection
criteria.
In the next module, we are going to learn the applications of software defined radio.
