Function Generator using X86 Microprocessor

Variable-Frequency-Waveform-Generator

EEE/INSTR F241 – Microprocessor Programming & Interfacing BITS- Pilani Goa Campus

DESIGN SPECIFICATIONS:-

  1. This system is used to generate a Sine/Triangular/Square waveform
  2. Frequenciesrangingfrom10Hzto99KHz.
  3. Voltage is between 0-10V.
  4. Desired frequency can be entered by pressing buttons provided on the keypad. For eg. To Generate a Square Waveform of Frequency 83.25 KHz the user has to press Square, Followed by 10K Key- 8 Times, 1K Key – 3 Times, 100 Key –2 Times 10 Key- 5 Times.
  5. When generate is pressed then the selected waveform of that frequency will be generated. If the user wants to change the waveform, he just has to press the desired Button
