In the previous lecture we have started about the time and frequency measurement.
Now we are going to learn about 37 units, the first question arises, what is the leader of the timing
of this is due to?
Because it's easier to measure voltage and current easily at lower frequencies, but it is difficult
to measure frequencies, for example, power of one thousand word.
Therefore, the lower skill is used to make calculations simpler and comparison is more useful than
aggressively used to express the full value of the power or field quantity to another on the laboratory
scale.
This can be a power issue or it can be an important issue.
The power issue decibel is 10 times toughest in terms of the ratio of P1 field, whereas V1 is just
one power and the second power.
So for example, if a device has an input power in and out to power is fuel there, it is even greater.
So for example, suppose if you want to find that during this, this is general fever upon field, whereas
in the case of amplitude ratio we have the square of the voltage that is very square upon the square,
not that is so square comes out of this great country or even upon Velone.
So please remember, in the case of power, it will retallack.
And in the case of voltage, it will continue because this causes a lot of confusion.
This will be more clear with the help of, for example, solar power.
And this one is calculated using this equation.
So let's try to find out the values.
Suppose we have an amplifier.
This is an amplifier.
You can say it is a positive effect and we have input of two signals and it's providing an output of
24 signal.
Let's try to find out what is the power of power in the deep.
So we have this formula now.
We are doing this everything in this formula, tangelo in the world.
And that is what?
To prevent very one, so that becomes then law then, too, and as we know, law and end is zero point
three zero one.
So this becomes ten multiplied by zero point zero one three.
That is equal to one giving so that the world becomes.
Three point zero one three living similarly for the kids, often do what they can, right PDV then.
Well, in.
There is and two, and that is 20, and it can be for 30 days, then 10, two plus 10.
And so this one is one.
And therefore, upon hearing you get 10 multiplexing
one point two zero one three.
So therefore, the total power in DV will be thirteen point zero one degree, so that twenty four will
be converted in thirteen point zero one three DB.
So using this equation, we can convert a power in the world to give very similarly.
In the case of DBM, the question is, do deviance tell 10 poverty level divided by one level?
Suppose we have a lot of power here and if we want to convert into DVM, then first we have to convert
to milliwatt.
So to equal to 2000 milliwatt.
So that would still be 10.
In that case, it wasn't.
And the value of this equation is then multiplied by three point zero.
To the point zero one three that is given its thirteen point, you want to that that value in the deal
between.
You want to do similarly, if we convert from divorc, then we get forty three point zero one zero to
DVM.
So using these two equations, we can convert the value to the next case.
We have to find out what is the gain of this device.
So as we know, the gains of the input, that is 20 to 30 then and now, we want to find the gain of
this device.
So gain.
And that is then Lovingston written.
And this quantity is one that is the so the game of these devices and giving this can be also verified
using the previous slides.
So in the previous link, we have seen that down to PowerGen divorce three point zero and three and
put the ten foot forward and give us ten point zero one three and put forward was thirteen point zero
one three.
So.
This was this was three point zero one three and this was thirteen point zero one three.
So when you take law, this this will be subtracted.
So the game will be 35 zero one three minus one.
You want three.
That is equal to in the sense.
The topower.
Similarly, this is a table to solve the poverty and poverty in what so it's hard to.
What would say if you do this thing, you can easily convert the room to vote in DP.
So next year, next thing that you have to convert to convert to DP and give them that, you pay the
police to do so.
15 more DHBs, eleven point seven, six, seven, six one and Devean is forty one point seven six.
So from this you can verify it is there is it is 30 more than this quantity.
So if you want to convert DV to give you just we have to let her do the giving, then it can be converted
to you.
So in this topic you have a study about 37 seven, which is one that is the mortgage one is completed
in this model.
What we have is 34 different parameters of a software defined radio.
We have to study about the software competition architecture.
We have studied SD and we have studied time and frequency domain analysis.
We have we study the software defined.
We do.
We have to study about the civilian use.
