Vin: 0V

Vout: +12V

VUT: 5V

VLT: -5V

🎯 Current Status

Hysteresis: 10.0V

Output State: HIGH (+12V)

VUT = +Vref × (R2/(R1+R2))
VLT = -Vref × (R2/(R1+R2))
Hysteresis = VUT - VLT

🔧 How It Works

Schmitt Trigger is a comparator with hysteresis. It has two different threshold voltages:

VUT (Upper Threshold): When input rises above this, output goes LOW
VLT (Lower Threshold): When input falls below this, output goes HIGH
Hysteresis: Difference between thresholds prevents noise triggering

📈 Key Features

Noise Immunity: Hysteresis prevents false triggering
Square Wave Output: Clean digital signal from noisy input
Memory Effect: Output depends on input history
Positive Feedback: Creates the hysteresis behavior

🎯 Applications

Digital Circuits: Convert analog to digital
Oscillators: Generate square waves
Noise Filtering: Clean up noisy signals
Level Detectors: Detect voltage levels with immunity
