Installing Wine for Running Windows Application in Linux

Wine software is interface between application software that running on windows os to application that running on Linux OS.
You can install wine from the official website https://www.winehq.org/  ,
Go to Download section, click

 

Go to Open Suse section, click

 Click on Open Suse, if you use open suse Linux, and choose another operating system that suitable.

Choose Open Suse version, in this case Open Suse 13.1 
or installing wine from YAST. YAST is menu manager configure hardware or software of Open Suse Linux.

 Click YaST

Enter Su Super User Password, the password when you install Linux.

choose software management or software repositories, click

Refresh....

 

Be patient, still refresh....

 Still reading...

 On search box, print wine and search...

 Wine software package pop up...

Accept and install...

Open Suse Linux

I installed Open Suse Linux on my notebook , sony vaio . I used OpenSuse Harlequin i586 version 13.2 . Instead of using windows operating systems, i am prefer using Linux or Unix OS. Because there so much alternative Operating System offered and it's all free and not easily affected by computer virus or bugs. And  a friend of mine using windows operating system and browser such as internet explorer and others such as chrome, mozilla, opera under windows operating system , there is problem with pop ads in browser , and it is really annoying and make the PC running slowly. Although, I have download ad blocker for mozilla, but it still not works, cause the annoying ads still come up.
and compare to linux, there is not such these problems.

although linux using open source software, there are many windows os software that can run in linux open suse with Wine software. Wine software can make software based on windows os run in linux os.

 later we will discuss how to using wine and download and running software with os windows operating system on linux.

linux running with low specification of hardware, and you can running your old pc 386,486 with linux and unix, with several limitation of application , if you using application software with big ram requirement. i am not experiment yet using graphical processing software such blended , etc.
what i want to show you, how linux can help me and you for running and helping your everyday works in office using libre office word processing and spreadsheet. with email and processing your document for everyday works.


Using Libre Office, the menu is user friendly, I am no problem switch from ms office to libre office, is the same office and function, and it support ms word 97 for saving my file and can convert to pdf also.support ms office 97/2000/xp/2003 document saving.

4G LTE Bandstop Antenna UHF Filter 703 MHz - 803 MHz

As from 4G LTE Band spectrum, we can see that at LTE Band 44 , allocation frequency of 4G LTE at 703 MHz-803 MHz. And this spectrum frequency , overlapping with digital TV spectrum. As we know, digital tv spectrum frequency at band 703 MHz - 803 MHz, with bandwith 100 MHz.
So the center frequency will be :

Center Frequency 703 - 803 MHz = 753 MHz

I use Bandstop filter calculator refer to http://www.wa4dsy.net/filter/filterdesign.html

 After we input the parameter of center frequency 753 MHz , and bandwith 100 MHz at calculator, then click compute parts as the menu on calculator, then we get the result of 3 filter design with 2 circuit , butterworth, bessel, and chebyshev.

The component values of  3 design filter, for butterworth, bessel, and chebyshev are :

 You can choose one of three offering design and choose one of two circuit for your implementation.
The output chart graph of filter design are :

3 Pole Bandpass Filter for uhf digital tv 470-800 MHz

This 3 pole bandpass filter using https://wetnet.net/rf_design/3pole.main.cgi  design calculator online.
this bandpass filter is butterworth filter and intended to filter digital tv bandwith 470MHz to 800 MHz , and only this signal will detected after antenna.

Parameter of filter :
Band Frequency 470 - 800 MHz
Center Frequency = 635 MHz
Bandwith = 400 MHz
Impedance = 50 ohm

Input this parameter to online filter calculator above :

 Click Submit , and the result :

L1,L3 : 0.008763 uH ( 8,763 nH)
L2      : 0.039789 uH (39.789nH)

C1,C3 : 0,000008 uF ( 8 pF)
C2      : 0,000001753 uF (1,753 pF)

We must determine for Inductor L1,L2,L3 the coil diameter, coil length and number of turn of coil.
Using online calculator from  http://www.qsl.net/in3otd/indcalc.html we can determine diameter, length and number of turn coil.
For L1,L3 :

L = 0,00876 uH , coil diameter will be  d : 0,01 m  , Coil length will be l  : 0.01 m and number of turns , n : 1,1355

And for L2 :

L = 0,0396 uH , coil diameter will be d : 0,0259 m , coil length will be l : 0,01 m and number of turns n : 1,1355

The most important thing of build filter is the connection between component should be as close as possible, for avoiding wild capacitance that will generate noise, and the ground area of PCB should be good and wide.
On the next article, I will posting the implementation of this filter.

Chip LSI internal configuration PPI 8255 shows the figure 1. In figure 1, pin IC 8255 consists of 3 groups:
1. Read / Write Control Logic
2. Data Bus Buffer
3. Input / Output Ports

READ / WRITE CONTROL LOGIC

Groups Read / Write Control Logic organize all data and controls, both internal transfers Form and Form of Transfer externally. ACCEPT singer group input from address bus and bus control CPU, the group later realize Ke - Control group. Pin - pin Of The Read / Write Control Logic is as follows:

CS (Chip Select)

Low ON signal pin singer will be to enable communication LSI Chip PPI BETWEEN 8255 TO microcomputers.

RD (Read):
Low ON signal pin singer will be to enable the CPU to review read status information OR Data From Chip LSI PPI 8255

WR (Write)
Low ON signal pin singer will be to enable the CPU to write a review OR Data Into PPI control word 8255
A0 and A1:
The input selector is functioning as part of the Joint Control word - the same WITH RD and WR. Basic Operations The Group is controlled by the Read / Write Control Logic singer portrayed ON the table below.

re:
ON logic high reset input will be to clear the contents of the list of controls and harbor ALL To set the input mode.

Control Group A and Group B:

Configuration functions From EVERY port in the software program by. IN AN basically CPU provides output control word addressed to the LSI Chip Control Word 8255. PPI mode provides information about, bit set, bit reset, And Others. Singer configuration is used to initialize the configuration functions review Chip LSI 8255 PPI.

EVERY Control blocks (Group A and Group B) RECEIVE command From the Read / Write Control Logic, And said menerimacontrol Data From internal bus (internal data bus) and execute commands - Commands Right to review arrangements port - port ITU. ON said control registers can only perform write operations, NO can perform read operations.

DATA BUS BUFFER
The data bus is a 3 state buffer 8 bit With operations Operating prayer Arah (both directions), ayng used to review 8255 WITH connect Chip PPI data bus system. Data Sent and received through the data buffer bus, Similarly to review the control word.

PORT INPUT / Output
Port Input / Output Was Part Of The 8255 PPI chip serves as a liaison
