Pls.... answer me the given below Ques...
expecting an approximate ans....

Hi anoop,

you given two transfer functions but you didnt mentioned is they are in parallel or cascaded.

they are not cascade or parallel in fact they are independent & we need to find a separate analysis of their bandwidth
thankyou......

find roots of s. so you will get equation of the form 1/(s-a). it's inverse laplace is e^-at. where 1/a is the 3dB bandwidth. for the seond equation it's the differentiation of e^-at so i dont think it's 3dB would change.

i am not sure whether my above approach is right.

I think it could be found by substituting jw for s then finding its magnitude and equating it to 1/√2 times its maximum magnitude... hope i'm right...

Hai lordsathish,

Hai amriths04,,
I didnt get you pls clear me.........

the capacitor voltage equation contains e^(-t/Rc), where 1/RC is the 3 dB frequency. analogous to that is what i told.
