Abstract:-
A signal generator is used in many applications in electronic measurement and teaching. Many types of signal generators are in a fixed operating mode with limited utilized signals. This research aims to design a highly accurate multi-functional, multi-waveform economic signal generator based on an Operational Amplifier (OP-AMP) that can provide waveforms commonly used in electronics experiments. The output values of the waveforms of the signal generator are square, triangle, and sine wave, and the output frequency was obtained in the range of (50 Hz- 4 kHz). The signal generator designed in this paper is a simple, practical experiment with low-cost features and an important application. A circuit of generator based on OP-AMP employs resistors and capacitors to shape the output signals. Additionally, a volume control component is integrated to allow for easy adjustment of the frequency. The research achieved good results for sinusoidal, triangle, and square waves, where multiple frequencies up to 4KHz and different voltage peaks at +5V, +10V, and +15V were obtained.
