Build the circuit using the LM$324$ Op$-$Amp using $R_1=1k$;$R_2=3k$;$R_3=2k,C_1=1F.$ Using the wave generator as the input with $V_{PP}=20V$ with $0$ V DC offset, frequency $f=300Hz,V_2=2\mathrm{.}5V$ and $V_G=-5V$ and $V=2OV$

Calculations: For the circuit determine and sketch the output signal designating appropriate $($calculated$)$ voltage points on the graph $($Vpp$,$ Vmin, Vmax, Vswitch $(0\mathrm{.}2$ pts $).$ Calculate the output signal duty cycle $($time for which op$-$amp is ON vs time it is OFF within one period$)(0,2$pts$)?$ Change input p$iameters to achieve duty cycle of about $25\%(0\mathrm{.}6$ pts $)$
