    Lissajou patterns

    Frequency determing patterns? i some time wonder why do we call them lissajous? ;D ;D ;D

    JOB INTERVIEWS

    hi MP! it seems that u have been conducting interviews. any tips for me as a candidate like how to behave in an interview? what factors u look for in the candidate? attitude,aptitude,knowledge?what percent of each? thanks!

    JOB INTERVIEWS

    DOES  any one of you have a sort of question bank or a set of technical questions asked in  multinational companies of electronics? Your personal experiences are also welcome.i am going to face them in near future thanks in advance! ;D

    Microcomputer

    Hi source2! It is a good idea i admire it. It can be done but u will have to design a big interfacing circuitary  consisting mostly of buffers and gates which can drive next level comprising of your RAM  and ROM .Make sure they are not loaded  or overdriven. Moreover impedance must  be matched...

    zilog z8

    hi  there! \many of the controller application examples are availabale on this site as well as others  in microcontroller sections. regarding the choice of programmer u may use a platform called proview 32  (u should know the basics of  C ) once the code is ready just burn it in the ROM.

    Hum in the incoming signal

    may i know the size of your antenna? it is definitely related to the amount of hum you hear. It should be small in case of microwaves.

    zilog z8

    hi friend! i dont understand whether u are using zilog or intel processor as the controller in your project? Any way both are similar in working just companies differ. May be i can help u more in Intel and Atmel.Can u tell me the project u have finalized? ;D

    transistors

    hi kevin ! i too dont like non linearitities. lower but linear beta is better for me. hi audioguru! that means By changing emitter resistor we can change the gain of the transistor. Whats the problem if we make extremely low Re?Do we have biasing problems? or we may use high Rc? Actually i wish...

    80x86

    Just think of controlling a stepper motor to move in steps according to your desire or a given motor rotating through an angle fed by you through the port. or a panel of LEDs glowing in  a particular fashion. ;D

    conversion from miliohms to voltage circuits

    right there the path from milli to Megas! i have however seen from 1 ohm to say 10 mega ohms thats it thanks for the info guys! ;D ;D ;D

    transistors

    Hi audioguru! do we require a high or low beta for a high gain amplifier? How do we chose beta for a given application? ;D

    zilog z8

    then u might have to study the pin assignment diagram and perhaps the datasheet .u may have to buy an explanatary book for it from the market if u have not got one along with it. I have not worked on zilog processors i use Intel and sometimes Atmel. Although pin assignments are only a little...

    zilog z8

    many articles here say the same thing. controller is a full PC u can use all its features. for any control application just like a stepper motor or even an induction motor. ;D

    conversion from miliohms to voltage circuits

    hi there! i guess audioguru's answer is 100% correct. but milliohms?where do u come across such low value resistance? audioguru, i have seen commercially available resistance minimum of 1 ohm.what about u? ;D

    transistors

    hi kevin! we use negative feedback through an emitter resistor just to stabilize the gain and make the amplifier much more linear. and to increase the range of i/p signal. ;D hi audioguru! do we have any disadvantage of a transistor with 2000 value of beta as amplifier or is it an excellent...

    transistors

    hi audioguru! here we reach a conflict ,for a good amplifier we need a low Re (emitter res) as u said and at the same time low Re causes the transistor to limit the i/p signal below a certain value. higher value of Re enables us to feed a gignal more than say 1 V. ;D

    transistors

    hi audioguru! i feel that it is the value of beta which is responsible for determining the gain of the transistor. It is its high value which makes it a good amplifier. ;D

    hi  harikannan! What is the application for which u are building this machine? SYSTEM INTEGRATION!

    80x86

    hi there mrohler! Both of 80386 and 80486 are microprocessors. U can use them both for any control application u can think of. ;D

    mod-5 counter

    hi digital! u r yourself digital ! anyway for mod 5 counter u need 5 t states and 3 JK flip flops. Do u need a definite pattern to be followed while counting like from 0 to 4 or something like that ? ;D
