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 -
deviation depens on the modulation index we chose.
;D -
high frequency means less wavelength and hence lesser height.

hi friend if that is the case,for what is the shannons theorem?
c=bandwidth*log(number of symbols)?
;D -
yea !

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. -
Does a bandwidth of say 10 MHz mean same as 10 MBps?
Does 10 Mhz have a meaning as such -
hi Mee!
What kind of modulation are u using for your signal?
In case its FM u have to compromise with the range -
what limits the rate of transmission along a channel?
-
A/D is a conversion process which consists of sampling ,quantization and coding while in the end comes a modulation technique like PWM.

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? -
But it is always advisable to keep ground at 0 rather than a negative supply!
-
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. -
Shannons theorem gives the relation that means a xhannel digital with 20 Mhz bandwidth does not carry meaning
-
here too they teach in bachelors and in masters too
-
electrical prerequiste for electronics and electronics for computers! ;D
-
no i mean does it make sense to say that my computer has say "B" Hz of bandwidth?
-
we do it in our engineering bachelors and in masters here in india...
-
even in computers we need vast knowledge of electronics .world is converging dear!!!

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? -
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. -
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? -
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. -
behavior of the transistor to unexpected surge voltages is also important to know when designing
10kHz FM modulation
in Theory articles
