QUESTION $5$

Using the components available in the practice kit, assemble the circuit shown in the figure. The component values are R $=560$ and C $=220$ nF$,$ and the operational amplifier power supply voltages are $+15$ V and $-15$ V$.$ Use a sinusoidal input signal with an amplitude of $2$ V and vary the frequency as indicated in each option.

Reason properly, based on the measurements you take, whether the following statements are true or not: a$)$

The circuit functions as a low$-$pass filter, attenuating high$-$frequency signals and allowing low$-$frequency signals to pass through.

b$)$

At an input frequency of $100$ Hz$,$ the output will show an amplitude similar to that of the input signal, with a phase difference between the two signals.

c$)$

For input frequencies of $500$ Hz$,1$ kHz$,1\mathrm{.}5$ kHz$,2$ kHz$,2\mathrm{.}5$ kHz$,$ and up to $10$ kHz$,$ the amplitude of the output signal will progressively decrease as the frequency increases, showing an attenuation trend.

d$)$

In a graph of the quotient between the output and input amplitudes as a function of frequency, the ratio between the two magnitudes tends to be less than $1$ for frequencies above $1$ kHz$.$
