guys hello everyone the topic is such a bar

00:00:06

f.m.

00:00:07

for the receiver in 202, the scale stretching

00:00:13

started once I’ll show you how it works and then

00:00:16

I’ll tell you the idea itself, here’s the

00:00:21

sadness in my heart 80

00:00:30

[laughter]

00:00:37

and this is

00:00:40

[laughter]

00:00:52

floor 5 entrance fifth floor no one has

00:00:58

been here yet

00:01:00

because Victoria is an old school send

00:01:10

as you can see the work of the noise suppressor also

00:01:17

for the fact that there are no seams

00:01:22

[music]

00:01:36

[music]

00:01:39

purchase

00:01:41

[laughter]

00:01:55

panties and a new mascot the company will soon,

00:01:59

as of course, let the benefit of my trip

00:02:00

technical composition

00:02:03

highlighted the cartoon of the year installation tape

00:02:06

theory of the decline of the director

00:02:08

and Dima immediately rent peak

00:02:10

drinking chestnut pilots go

00:02:14

quite according to beer etiquette in a

00:02:17

restaurant you can’t drink a lot of beer

00:02:26

[music]

00:02:36

[music]

00:02:38

and

00:02:40

[music]

00:02:43

as we are here 90 8 megahertz the last

00:02:51

station in our region I hope from eight

00:02:54

years old tie autoradio

00:02:59

radio dacha

00:03:03

[laughter]

00:03:12

and

00:03:22

as well as in the hands of those who used

00:03:33

[ music]

00:03:39

photographs they were not poor people, then the

00:03:51

same moment we select antennas almost

00:04:00

to zero all the walls of some stations

00:04:03

will no longer receive

00:04:09

[applause]

00:04:18

[applause]

00:04:20

tomorrow in Moscow, according to the Phobos center, we do

00:04:23

n’t expect red-hot precipitation

00:04:42

[laughter]

00:04:50

[applause]

00:04:51

[music]

00:04:56

looks like

00:05:22

this, I’ll explain how the stretching was done and

00:05:27

it’s so interesting, son,

00:05:35

we’ll connect this very bar to an oscilloscope

00:05:44

[music]

00:05:47

and in general tell us

00:05:54

when they connect directly to the lenses from their

00:05:58

generator, then the scale from the edge to the left of the edges of the

00:06:04

servants is all in stock and at the same time the entire

00:06:07

range is not rebuilt, this is connected

00:06:10

with what with the fact that the capacitor has the

00:06:17

property of operating on an alternating voltage, it

00:06:23

also has a reactance

00:06:25

on an alternating voltage; this

00:06:30

resistance depends on the purity, the

00:06:33

higher the frequency, the lower the resistance,

00:06:36

the larger the capacitance, the lower the resistance still

00:06:40

turns out when we rebuild the

00:06:43

capacitor, which gives it a maximum we have

00:06:47

long wires from the generator and the

00:06:51

wires start to fly and the capacitor

00:06:57

turns out to be like when it wasn’t done for future use,

00:07:02

I

00:07:07

made a device based on the similarity of the capacitor that

00:07:14

is rebuilt,

00:07:17

which means the range is here now, there is

00:07:21

a varicap now look at what is on the

00:07:23

state capacitor 218 kilohertz,

00:07:33

fix it

00:07:49

like this

00:07:54

218 others kilohertz and when we

00:07:59

rebuild we change the amplitude of

00:08:18

the capacitor

00:08:22

there is no plate itself before

00:08:27

and due to this it is processed you

00:08:31

release the voltage directly to the

00:08:34

varicap of the hour I will show you the bar

00:08:45

also the second model here it is

00:08:48

the bar the microcircuit receiver is all the

00:08:53

same Kostusev 4-34

00:08:58

added one more microcircuit in

00:09:02

particular this logic works like a

00:09:05

generator; in principle, a ready-made block can

00:09:11

already be used; it works; we

00:09:16

heard it quite well when we developed it;

00:09:24

we used the multisim program; this

00:09:31

program means a simulator; here

00:09:37

we see the oscillogram;

00:09:41

we now have the capacitors at maximum, and there seem to be

00:09:45

two capacitors; why two,

00:09:49

because it’s time a cyst and a double

00:09:51

capacitor and now at the maximum

00:09:56

here we see a voltage of 380 380

00:10:01

millivolts, say at 180 and we begin to

00:10:06

change the value of the capacitors we see we have an

00:10:12

apple growing there now about this

00:10:14

direct

00:10:16

constant here which is already there and

00:10:20

we have a voltage of two and a half volts 24

00:10:23

two with half a volt I again add,

00:10:26

for example, 50 percent, but

00:10:33

in our movement it drops to one volt and the

00:10:36

second capacitor is even less, in

00:10:44

principle this is the know-how, but it

00:10:48

was invented on this, perhaps that’s all, thanks for your

00:10:55

attention
