1.)Construct the circuit below selecting an RC combination such that RC [math]\displaystyle{ < 10^{-4} }[/math] s

2.) Adjust the pulse generator to output square pulses which at [math]\displaystyle{ \tau }[/math] sec in time.

3.)Measure[math]\displaystyle{ V_{in} }[/math] and [math]\displaystyle{ V_{out} }[/math]. Sketch a picture comparing[math]\displaystyle{ V_{out} }[/math] and [math]\displaystyle{ V_{in} }[/math].

4.) Change the pulse width such that [math]\displaystyle{ RC = \tau }[/math]

5.)Measure[math]\displaystyle{ V_{in} }[/math] and [math]\displaystyle{ V_{out} }[/math].Sketch a picture comparing[math]\displaystyle{ V_{out} }[/math] and [math]\displaystyle{ V_{in} }[/math].

6.) Change the pulse width such that[math]\displaystyle{ RC = 10 \tau }[/math]

7.)Measure [math]\displaystyle{ V_{in} and V_{out} }[/math].Sketch a picture comparing[math]\displaystyle{ V_{out} }[/math] and [math]\displaystyle{ V_{in} }[/math].

Questions

1.) What happens if than amplitude of [math]\displaystyle{ V_{in} }[/math] is doubled.

2.) What happens if R is doubled and C is halved?
