hello all im new here so i dont know if this is the correct place for this topic so sorry for any inconvenience caused.

this is my question:

Use the small-signal model of the diode to predict the output voltages for the input voltages given. Plot a graph of | vout(t) | based on the small signal model.

Input Voltage 1 = 0.65 + 0.04cos(2*pi*200*t) V

Input Voltage 2 = 0.68 + 0.01cos(2*pi*200*t) V

0 ≤ t ≤ 20ms

i know vout = -Is*R*exp(vin/Vt)

How would you solve this? what basically is the small signal model? is it like a formula that I have to substitute these values in? And for the graph what goes on the x-axis and what goes on the y-axis?

I've got a diagram of the circuit if it helps for you to see:

Thank You.
