Construct a Schmitt Trigger using the 741 Op Amp

Draw the Schmitt Trigger circuit you constructed. Identify the values of all components

To construct the circuit above I am going to use the following components:

  1. [math]\mbox{OP}\ \mbox{AMP}\ 741[/math]
  2. [math]V_{ref} = 12\ V[/math]
  3. [math]R_1 = 1\ k\Omega[/math]
  4. [math]R_2 = 1\ k\Omega[/math]
  5. [math]R_3 = 10\ k\Omega[/math]

Graph [math]V_{out}[/math] as a function of [math]V_{in}[/math]. Is there a hysteresis loop?

Identify the input voltage threshold levels at which a[math] V_{in}[/math] will produce [math]V_{out} \approx V_{cc}[/math]

Compare the threshold values to what is expected.
