The function signal generator uses the integrated circuit IC8038 for signal generation. After filtering, signal amplification, relay network signal strobe, and resistor divider, it outputs square wave, triangle wave and sine wave with adjustable amplitude ranging from 0V to 10V and adjustable frequency ranging from 100Hz to 20KHz. The relay network is controlled by the single-chip STC12C5A60S2, and the signal selection and output are controlled by the single-chip microcomputer, too. The function signal generator can generate triangular, square and sinusoidal signals from 100HZ to 20KHZ. It has the characteristics such as low cost, good signal quality and easy operation, thus improving the intelligence level of the signal generator.
