hello everyone gudevening..can anyone help me on my research on the methods on how a single sidebands is being generated? plss i need the complete answer..thanks!
 

Re: communications 1

There are two methods:

1- Using Filtering
You generate a DSB signal and then apply highpass/lowpass/bandpass filtering to suppress one of the sidebands. The problem is that ideal filtering doesn't exist and thus the gradual cutoff of a filter causes partial suppression of the other band also !

2- Using Hilbert transform
You can search for it. It makes a 90 phase shift for all the spectrum and employs a certain block diagram, this is not ideally realizable because phase shift cannot be applied to the whole frequency domain.

using SSB but using voice this methode is gud .Incase of video this not gud VSB is gud
