SAŽETAK / ABSTRACT:
This project shows the realization of a signal generator using NE555, LM2902 quad-operational amplifier and RC low pass filters. Generated frequency range for this signal generator is 50 Hz to 4 kHz. Duty cycle of the square signal and of symmetry of the triangle signal is in range of 0.9% to 99.1%. Amplitude range and added offset both depend on the supply voltage of the circuit.
