Low pass filter
Simulate in the time domain and modify the frequency of the sinusoidal source. Observe the change in the output voltage (accross the capacitor) compared to the input voltage (to the left of the resistor)
Reset the simulation, observe only the output voltage and run a simulation in the frequency domain.
Observe the Bode plot, the amplitude and phase of the frequency response.
What happens if you change the value of the capcitor?
