dominent pole

[mateenashraf]

can any one of u tell me if a transfer function has two poles say fp1 and fp2 and if fp1 is very smaller than fp2 say fp2=4fp1 then how the 3db frequency is less than 6% smaller than fp1 plz reply any one of u coz i m having great confusion

I don't know about anyone else, but speaking for myself I cannot figure out what you're trying to say.

 

Let's say that [math]F(s)[/math] is the transfer function.

 

can any one of u tell me if a transfer function has two poles say fp1 and fp2

 

Are you trying to say that [math]F(s)[/math] has poles at [math]f_{p1}[/math] and [math]f_{p2}[/math]? If so then why not just call the poles [math]p_1[/math] and [math]p_2[/math]? And if not then what do you mean?

 

and if fp1 is very smaller than fp2 say fp2=4fp1 then how the 3db frequency is less than 6% smaller than fp1 plz reply any one of u coz i m having great confusion

 

And where do the numbers "3dB and "6%" come from?
