| Abstract | ||
| Function signal generator has a wide range of applications in electronic measurement and teaching. Yet, many of the trading tests signal generators are bulky and expensive. Furthermore, many types of them are in a fixed operating mode with limited utilized signals. The aim of this research paper is to design a multi-functional, multi-waveform with high accuracy economic signal generator based on operational amplifier, which is able to provide waveforms that are commonly used in electronics experiments. The circuit is simulated in Multisim software, and the hardware circuit is validated. The results show that using Multisim simulation results are basically consistent with the hardware circuit. The output value of the waveforms of the signal generator are square, triangle, sine wave with voltage range of (0-14 V) and output frequency range of (50 Hz-3.1 kHz). The signal generator has simple, practical, low cost features and the important application value. | ||
