Lab 6 Pulses and RC Filters

Differentiator

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

2.) Adjust the pulse generator to output square pulses which at [math]\tau \approx[/math] RC/10.

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

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

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

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

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


Questions

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

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

Integrator

Now repeat the above experiment with the resistor and capacitor swapped to form the low pass circuit below.
