  1. hi there! modulation index and deviation are interchangable. if i/p signal varies between 1 and 2 V,to what extent do we vary the frequency is in our hand. hence in our own hand. ;D

  3. deviation depens on the modulation index we chose. ;D
  4. high frequency means less wavelength and hence lesser height. ;D
  5. hi friend if that is the case,for what is the shannons theorem? c=bandwidth*log(number of symbols)? ;D
  6. yea ! jr. stands for junior member followed by a member, senior member and then electronics-god
  7. hi all! if bit rate is 10 MBps along the line what will be its bandwidth i mean the channel bandwidth. i am confused between the 2 terms.
  8. Does a bandwidth of say 10 MHz mean same as 10 MBps? Does 10 Mhz have a meaning as such
  9. hi Mee! What kind of modulation are u using for your signal? In case its FM u have to compromise with the range
  10. what limits the rate of transmission along a channel?
  11. A/D is a conversion process which consists of sampling ,quantization and coding while in the end comes a modulation technique like PWM.
  12. hi audioguru! we still use BJT in most of our analog cards here in india. i personally use a BJT as a better LED driver than FET.But dont know why?
  13. But it is always advisable to keep ground at 0 rather than a negative supply!
  14. Hi audioguru! can u tell me some points by which BJT is better than an FET? i guess FET has higher i/p impedance but BJT is better in one of the ways like these parameters.
  15. Shannons theorem gives the relation that means a xhannel digital with 20 Mhz bandwidth does not carry meaning
  16. here too they teach in bachelors and in masters too
  17. electrical prerequiste for electronics and electronics for computers! ;D
  18. no i mean does it make sense to say that my computer has say "B" Hz of bandwidth?
  19. we do it in our engineering bachelors and in masters here in india...
  20. even in computers we need vast knowledge of electronics .world is converging dear!!!
  21. hi guys! i just had a technical interview in a job interview. i was asked how will u study at night without using current and a combustible substance at your work place? answer:what about optical fiber cutting?
  22. hi audioguru! i carry out the Q point and hence the beta analysis for a transistor only in CE region. cause i use it mostly as my amplifier. for such a case i found the results which i just told.i too believe that a transistor is saturated when VCE is 0 i.e we move towards forward bias from reverse side. Ic is maximum.
  23. hi all! i wish to know what is the demarkation line between electrical and electronics engineering? i.e to decide whether an application is a subject matter of electrical or electronics engineering?
  24. hi anita! i recently did an industrial project on embedded systems .actually i used an embedded system for a control application ...basically u must understand that they are nothing but compact,industry specific microcomputers used for control applications. i always liked to play with my C software which i wrote for it and burned into its ROM. u can visit www.advantech.com to see how such systems look like.ofcourse theres large library stuff.
  25. behavior of the transistor to unexpected surge voltages is also important to know when designing
