Design a $2"*$ order Sallen$-$Key low pass filter with a maximally flat Q$,$ and a break$/$corner frequency of $1\mathrm{.}8$kHz$.$ Include the following in your design:a$.$ Circuit diagramb. Bode plot of the filter responsec. Utilizing pole distance or other stated method, calculate the gain of the filter at:i$.1\mathrm{.}3$kHzii. $3\mathrm{.}2$kHziii. $7\mathrm{.}2$kHzd$.$ For an input voltage of $1$Vrms$,$ note the output of the transfer function expressed in dB$.$@$16$
