Electronic Instrumentation and Operational Amplifiers

Schmitt trigger versus Comparator

 

1. What are the functions of OA1 And OA2

2. Calculate V_TL and V_TH for Schmitt trigger part of the circuit.

3. Make simulation for V_IN = 7×sin(2Π×10×t) + 1×sin(2Π×2000×t). Present result of simulation on time interval 1.0-1.3 sec.

4. Explain difference in output signals V_OUT1 and V_OUT2

OA1, OA2 - 741
+V_CC=+10V
-V_CC=-10V
R₁ = 1,0 kΩ;
R₂ = 9.1 kΩ;
