capacitor
the difference is that in polarized one you have to connect the +ve terminal of capacitor to the +ve potentian in circuit and so on.. but the nonpolarized one it doesn't matter
the polarized type is usually have large capacitance more than the nonpolarized ones
4 bit divider
Hi experts..
I have aproblem in designing an elementary calculator using logic gates IC's
There is no problem about addition,sub and multiplying
Can any one please tell me how to desing a circuit which can divid 4 bit on 4bit?
Thanks in advance..

I think that Mr.Kral is right
the K-map is avery good method to simplify comlicated expressions .. and you can feel it's benifit if you try to simplify any complex expression contains 4 variables as example using boolean algebra
Hi experts
i wanna desing a circuit which supposed to multiply 4bits no using the full adder IC and the clock and counter
there is no problem about the multiplying circuit .. but how can i use the same circuit of multiplying to perform the division also
Thanks in advance.
Yassorty,
hi
the full adder is an IC having no 74LS83 or 74LS283
this IC has 3 types of inputs the first is the first no u wanna insert to add to or subtract from it , the second is the no you wanna add or subtract the third input is the input carry which is equal 0 in case of first operation
And the...
hi
i have no good knowledge about antennas
but i think you can get what you want from the following link about the design of antenna
i hope you'll get your help there

Re: type of feedback
hi
i think your problem about the feedback current involved with transistors and the methods of biasing
i think you will get what you want if you search for transistors and the methods of biasing them
Re: RF choke calculation
I'm not expert...
But as far as i know, RF Chock coil can be simply a coil wonded around ferrite core too many times (say 300 turns on length of say 2cm)..
It is like blocking capacitor, you don't need to calculate it exactly, unless you wanna block certain freq...
opamp subtractor circuit
Op Amp???
I want a digital one...
And wanna display output on 7-segments display..
What i wanna is one with some AND's/OR's....other digital ICs..
Thanks in advance,

Hi experts :)
I want to learn digital design from scratch, what's your advice to me to go in??
I 'm still newbi, first year electronic engineering student....
Hope to get simple and effecient help :)
Thanks in advance,
