    Abstract :

    Abstract — The main process of this research is to design and fabricate an extremely low cost, small sized, accurate and versatile function generator up to 17MHz with frequency resolution of 1 Hz by using minimum components like IC MAX038- analog function generator along with digital frequency counter implemented by PIC16F876 microcontroller and 2×16 characters LCD. External amplitude/duty cycle is controlled by ICs LT1364[1] and NE5532N[2], with the following key features: 1Hz to 17MHz operating frequency range, sine, square and triangular waveforms, independent frequency and duty-cycle adjustments, 15% to 85% variable duty cycle along with 50% fixed duty cycle, low-impedance output buffer, low temperature drift. In this research, the complete design of the function generator is provided. Hardware and software technologies are integrated to fabricate this instrument.
