Simulation $3$: Low Pass Filter

A low pass filter consists of a resistor and a capacitor in series, across which an $AC$ input signal is applied. A load, comprising of a $1M$ resistor is applied at the centre tap between the R and C components, across the capacitor. Two sets of filter component values need to be evaluated:

i$.$ Resistor $-1k,$ Capacitor $-200$ nF

ii$.$ Resistor $-1000$ ohm, Capacitor $-800$ nF

a$)$ Create the two circuits mentioned, separately on SIMetrix and copy$/$paste them into your answer sheet. $[10]$

b$)$ Simulate the two circuits with a $20V_{p}AC$ sinusoidal signal, sweeping the input frequency from $20$ Hz to $1\mathrm{.}5$ kHz $.$ Provide a snapshot of the output voltage vs input frequency waveforms. $[10]$

c$)$ What difference do you notice between the two circuits? Discuss. What is the implication of this finding? $[5]$
