    Come on guys i was serious and everybody played a joke on me.... HAHAHAHA

    PNP and NPN replacements

    hi walid ! it is a golden rule in electronics that NPN and PNP transistors can be interchangably used in any electronics circuit by slight modification. But in general we go for NPN transistors including me and u know the reason behind this is too simple------- "Electrons have higher mobility...

    Op.Amp. vs. Diff.Amp.

    by using the word linear here,do you mean a linear operation like i/o slope is constant? like constant increase in o/p leads to constant increase in o/p?

    Weather Station

    individually u can get the circuits for these try searching on google for 1.aaroncake.net 2.beyondlogic 3.hobby circuits may be electronics lab too.

    Orcad Layout

    Have you made sure that Netlist and design rules check have been saved?atleast created!!! I have worked on ORCAD LAYOUT as well as CAPTURE and never faced such a problem....

    Op.Amp. vs. Diff.Amp.

    Then why do you think we call them as linear ICs. I mean any vendor would say 741 linear IC unlike any other IC.

    Op.Amp. vs. Diff.Amp.

    hi alun! i guess digital - analog and linear -non linear are two different clasifications. as far as i know opamps are always linear.

    switching diode

    diodes bidirectional characteristics are basically explioted to use it as a switching device. It has applications in many domains right from controllers to inverters. where do u wish to use the diode?

    Op.Amp. vs. Diff.Amp.

    I had a misconception that it is their manufacturing process which makes tham called so i.e linear ICs. It is because that they operate linearly. thanx buddies!

    basics of electrical supply

    Conclusion from my side : A high voltage source with a less series resistance or a high current source with high parallel resistance kills u.in otherwords it is V*I.

    MICRO ANTENNAS

    Higher frequencies need higher bandwidth .Is it according to shannons theorem u are talking about? bit rate bandwidth relation?

    Op.Amp. vs. Diff.Amp.

    Any other ICs which are called linear Ics along with op amps?

    MICRO ANTENNAS

    ok. now i understand. But I have also studies that we are constantly moving towards hisher frequencies in communication.Anyway,what are the disadvantages of communication at say 10GHz than at say 100Hz?

    basics of electrical supply

    hi MP ! I think the 1000V source about which u are talking might be haveing a high internal resistance which dissipates most of the power when u touch the source. It does happen .Some lineman do repair high voltage lines with bare hands but internal resistance must be high otherwise god is the...

    basics of electrical supply

    hi alun! also the skin effect also dominates at very high frequencies and does not damage the inner organs. (considering body to be perfect conductor)... ;D

    Op.Amp. vs. Diff.Amp.

    Are the simple FETs and BJTs which we use non linear amplifiers? By linear do you mean Y=m*X kind of relation? or in otherwords gain independent of input? i think u are right gain of a single transistor amplifier depends on i/p level.

    MICRO ANTENNAS

    HI AUDIOGURU! my original question was that why dont they further shift the frequency range up and further reduce antenna height.

    Op.Amp. vs. Diff.Amp.

    hi audioguru! we generally call opamps as linear ICs . Do u know why is it so?

    MICRO ANTENNAS

    hi there all! can anybody tell me the logic behind fixing up 88-108 MHz as range for FM? and why not some other range?
