Square and Triangular Wave Generator with Positive & Negative feedback with power supply (using OP-AMP) Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12273
Indian Lab Suppliers supplies the Square and Triangular Wave Generator with Positive & Negative feedback with power supply (using OP-AMP) (Product ID: 12273) as part of its electronics engineering lab equipment range. It generates square and triangular waves from a Schmitt trigger, an integrator and an inverting amplifier built on IC 741s.
Quick Answer
The Schmitt trigger uses positive feedback to switch its output between two levels, and the integrator, with negative feedback, turns that square wave into a triangular ramp that is fed back to the trigger, so the loop oscillates. An inverting amplifier stage completes the circuit. Potentiometers vary frequency, amplitude and duty cycle, and the waveforms are viewed on a 20 MHz CRO (not included). The board has three IC 741s and a ±15 V DC, 50 mA supply wired internally.
