Vo=f(Vi) transfer characteristic figure is on above picture.
Design the circuit with ideal diode.
When input source frequency is implemented Vi(t)=5.sin2π1000t V
Draw circuit's output signal?

Guys this is my last pre-lab question. I cannot solve this. I need to help.
 

10 ohm or 10K ohm? I cannot understand clearly
 

10 or 10K does not matter considering only the threshold voltage drop of a diode.
 
Okey I understood design logic and created another circuit maybe helpful for new learners.

Hi,

Design the circuit with ideal diode.
Click to expand...
What does "ideal diode" mean?

In my eyes an ideal diode has no voltage drop.
But then ... how to generate a 2V threshold?

A diode model can be simple and ideal, or we can add behaviors that make it closer to a real diode. To create a voltage drop, the diode automatically adjusts its internal resistance. Suppose supply V is 10V, and series resistance is 10 ohms. Then we want the diode to have 2V, and the resistor to have 8V. This fixes Ampere flow at 0.8A (=8V/10). The diode automatically adopts its internal R of 2.5 ohms (=2V/ 0.8A).

Or now suppose series resistance is 10k. As before the resistor gets 8V. Current is 0.8mA (=8V/10000). So the diode adopts its internal R of 2500 ohms (=2V/ 0.0008A).
