Baseband to bandpass modulation

[tabraiz]

is it necessary to convert bits into baseband before bandpass

 

[Communications_Engineer]

no, bits are in baseband (I hope you know the difference between base-band and pass-band)

 

[tabraiz]

dear All,
Bits are 1010101010101010
BaseBand is RZ, NRZ, AMI

 

[Communications_Engineer]

no, not really, both are base-band. Thats why I said you need to know the difference.

Base-band signals generally occupy entire bandwidth available to them, reason is that they are digital and digital signals will need all the bandwidth (although we can reduce this)

 

[tabraiz]

Baseband can occupy DC to few MHz is this a Right Statement

Added after 15 minutes:

if u are of the view then why Line codes are required

Thanks
You are right, about Baseband definition, I have quoted the definition from SKLAR but still some misconception, Is it possible to send a baseband signal from one place to another thru some baseband channel without Line Coding

 

[tabraiz]

Oh! Great.
That means Still in Hard Drives NRZ is used that indicates there is no application of Un modulated signals ie Bits ???

Thanks
