Programming in simple terms

Coding is a mystery for many... even a number of engineers merely got used to coding and yet can't explain how it works for a non-engineer....
 
a programming code is a language created by humans to interact with a computer.  Instruct it to do what tasks you want. The computer itself works on combinations of 1s and 0s (binarry numbers) meaning on and off switchz. It is basically made of switchz (transistors) that interacts with one another to perform tasks. A human will need to have super powers to instruct all these billions of switchz to get the computer functioning with all the tasks needed. Therefore, a  programming language is created to ease the process.

Notch filter Lt spice

This is what i am working on right now a 3rd order inverted filter. well i am trying to figure out the correct component values to have a 500Hz notch filter . while using f = 1 / 2*pi*R*C .
R=R1=R2. R3=.5*R
C=C5=C6 . C4=2*C

it is strange that the graph isn't giving me notch graph. Perhaps i did something wronge

Robert Noyce

Robert Noyce 

12 December tot 3 juni 1990

co-founder of the two multibillion companies Intel and Fairchild Semiconductor 

Piloted his own jets and has 15 patents.

co-inventer of the Microchip, the heart of every modern computer, automobile, cellular telephone, advanced weapon, and video game.

what made him use his inner human potentials ? Perhaps the book may answer the question, I will get it soon.. once am done reading it i'll post my review on it , i couldn't find another book talking about his biography then the above.


I believe if he did it we engineers kan do it

Incandescent Light Bulb

the lamp acts like a resistor. It gets fed by voltage and outputs current , it gets fed by voltage till it get so hot that it starts glowing. 

BroadBand , PassBand ,BandPass , BaseBand & BandSTOP!

Salam alaikom,

Currently going through my favourite subject which is Computer networks ( networking engineering or telematics), actually preparing for a retake which will be held on thursday as last exam for the year! actually the one befor the last. the last is digital signal processing which is a story for another day.
 so i wanted to pass to you 4 definitions of terms which always played tricks on me.

BroadBand
It is a telecommunication technique used to determine the capasity of data transmission. It allow multiple channels to be used within one bandwidth of a medium (i.e coaxial cable). The best example of broadband is the Tv cable. The cable is broadband. Why? because the bandwidth of the cable can view more then one channel. So when you  are changing MTV to Peace Tv actually you are changel frequency to frequency. This method Tv cable method is called Frequency-Division-Multiplexing. Because the bandwidth is divided (multiplexed) to differenct channels\frequencies.  This method deals with analog signals only.
   BroadBand can be seen as a multiple of basebands.

BaseBand
It is a telecommunication technique used to determine the capasity (bandwidth) of data transmission. Over one bandwidth of the medium One communication happens. One types of information. i.e Only one phone call.
In low pass filters. the term is also used to describe the frequencies from zero to the Cut-off frequency. ( the frequencies which are passed).
  Ethernet (802.3) uses baseband because it is simpler.

BandPass
it is a filter which is a combination of low pass filter and high pass filter so it passes a bandwidth u set by setting the values of the components you use to make up the circuit . It can be constructed of LCR or RLC.

PassBand
Is the frequency passed through a bandpass filter. also can be caalled as BandPass signal.

Bandstop
It is a filter which rejects a range of frequency and passes others. It is also called Notch filter. Notch filter is used to remove the 50Hz. 50Hz in many cases us noise( unwanted signal) which is generated from the outlets or power supply.
That is simply what it is. You can dive deeper in it. Consider the above as a starter. At the moment of writing this article i was concerned about knowing the difference between Broadband(modulation) and badeband transmission because it is related the the PHYSICAL LAYER in the OSI module. because the physical layer is more concerned with the capacity of transmitting. Which makes for instance a fiber optic different from coaxial cable. Both are same as medium in term of propagating information.

cheers.

Stereo ..... Frequency Levels

What is a stereo ? 

i came across this question when trying to understand the Radio data system and how it works on . while reading this (RDS operates by adding data to the baseband signal that is used to modulate the radio frequency carrier. The baseband signal consists of a number of components. Firstly there is the mono audio consisting of the left plus right (L+R) component that is transmitted at the normal audio frequencies up to 15 kHz. The stereo difference signal is then amplitude modulated as a double sideband suppressed carrier signal at 38 kHz).

ok . there are two kind of stereos

Audio stereo and Video stereo

both refers to a similar term

Audio stereo : stands for sound being dividied into two separate channels (speakers) for the aim to support the sound simultaneously in two speakers to also provide the chance to mix different sounds. the idea is inspired because a human has two ears trying to make it realistic as much as possible. such as in a movie when a car passes the audio is divided in a way to give a sound (Doppler) from an ear to ear as the car is realistically passing in front of the audience.

Video stereo : two saperate images of the same objects, being taken slightly different in order to simulate 3D view for human eye. there are many different ways to get to the 3d effect which i wont discuss here

here is a good illustration klik here
Frequency levels. 
there are three weeks ahead of me to end the third year of applied communication engineering , one year ahead of graduating and i still do not know under what frequency lies the low , high frequency!!!! but i do know that microwave(not the range but the one u use ate your house) is the most used frequency in the world 2.4 gigahertz 

Designation	Abbreviation	Frequencies	Free-space Wavelengths
Very Low Frequency	VLF	9 kHz - 30 kHz	33 km - 10 km
Low Frequency	LF	30 kHz - 300 kHz	10 km - 1 km
Medium Frequency	MF	300 kHz - 3 MHz	1 km - 100 m
High Frequency	HF	3 MHz - 30 MHz	100 m - 10 m
Very High Frequency	VHF	30 MHz - 300 MHz	10 m - 1 m
Ultra High Frequency	UHF	300 MHz - 3 GHz	1 m - 100 mm
Super High Frequency	SHF	3 GHz - 30 GHz	100 mm - 10 mm
Extremely High Frequency	EHF	30 GHz - 300 GHz	10 mm - 1 mm
