Q1:

A second order active bandpass filter can be obtained by cascading LP second order filter having higher cut off frequency fOH with a second order HP filter having lower cut off frequency fOL provided

A fOL < fOH

B fOL > fOH

C fOH = fOL

D fOH < 0.5 fOL

ANS:A - fOL < fOH

If fOL is less than fOH, a passband will exist from fOL to fOH .
