This circuit is an active high pass filter which pass high frequency signal while rejecting low frequency signal. At that

time, input was unit step function and derived $2^($nd $)$ order equation. This time, input is

AC signal and R$,$C values are adjusted for simple calculation. Please derive gain

Leave $\backslash$omega as variable$=$

$(1)/(\_(0))\backslash$deg and $\backslash$omega $=1($ra$($d$)/($s$))[10$ points$]$

$($Let$\text{'}$s assume opamp is ideal. For the gain expression, use rectangular form for both

numerator and denominator$)$
