So that means we can represent binary '1s and 0s' with two distinct pulses which combine to form one period. and taking inverse of that period '1/2T' gives us minimum bandwidth. Is that right?

When we use pulse code modulation , it is said that the min bandwidth requirement is half the transmission rate. Transmission rate given in Bits/sec. But why?

http://www.seas.ucla.edu/dsplab/sqc/over.html It says we have to normalize a signal before it is fed to a compander which reduces its dynamic range. But why don't we directly feed the compander block without normalizing the function first? Help Required.

In given figure of interpoles connection for a DC Machine, why the carbon brushes connected to the commutator are not placed in the Magnetic neutral axis? The given position will induce more sparking. Interpoles solution is from following website...

omg! what was i thinking. Lack of sleep yesterday night may be causing this weird behavior .

In the question below i know 200/480 V is rated voltage at primary and secondary side of a transformer, but '13' is what i do not know. Also how does the solution work out? i have tried every possible thing. Thanks(Sorry if i could not phrase my question in accordance to the pattern)

yeah now i can get a feel for it tx a bundle

I will be mindful in future but that thread doesn't answer my question either.

For the Image given, i have to calculate reluctances of air gap and core which depends on respective mean path lengths. For the left hand core, the mean path length calculated in the solution manual is 1.11 meter . However what I don't understand is that why is the length of the air gap included...

I am more concerned regarding the theoretical aspect. Why cannot we just take absolute permeability of any material? In fact i have started reading about transformers and there i found relative permeability.

Why we use relative permeability if we have absolute permeability in electromagnetism?

I want to study "motors" , "generators" and stuff like that.

I want to study "Electrical Machines" Course. I looked for online courses but they all had different prerequisites to study "Electrical Machines" course. Can anyone guide me about what prerequisites are needed to study "Electrical Machines" or any specific contents that i should study (e-book or...

When choosing Line Codes (e.g. Bipolar or Polar formats) for transmission of bits over a communication channel such as twisted pairs, it is always desirable that no DC component is present for a particular choice. According to William Stallings (Digital Communication Book) "With a dc component...

So that means it is done to get economy and avoid complexity.
