Design a basic low pass RC filter to condition PWM analog output to a variable voltage. The passive

RC filter is suitable for an analog output that does not draw much current.

Consider that the PWM signal is generated at a frequency of $10$KHz$,$ an that it is to be used

with a first order system that has a response time $($time constant Tau$)$ of $0\mathrm{.}16$ seconds.

$[5\%]$ Calculate the level of ripple when the filter$$s corner frequency is placed in the middle between

the process corner frequency and the PWM frequency.

$[5\%]$ Calculate the filter$$s corner frequency to make the ripple $104$ times smaller than the original

PWM signal, e$.$g$.0\mathrm{.}5$mV ripple for $5$V PWM signal. PWM frequency.

$[1\%]$ Compare both cases above and comment which design is preferred.

$[1\%]$ Find values for R and C in both cases
