Аннотация

This article describes the design and construction of a low-cost, hardware-based variable frequency oscillator (VFO) for wave experiments in educational labs. The circuit uses operational amplifiers (op-amps), resistors, capacitors, and a potentiometer to generate sine, square, and triangular waveforms with adjustable frequencies ranging from 10 Hz to 50 kHz. Testing demonstrated a frequency stability of ±1.5% and a total cost of under, making it accessible for schools with limited budgets. The design emphasizes hands-on learning, enabling students to understand analog signal generation, frequency control, and circuit troubleshooting.[1] Future iterations could integrate digital frequency displays for enhanced precision.
