Wave Form Generator

Study Project
Project I for Advanced Electronics
October, 2001

The aim was to analyze and implement a standard time-base wave generator that would produce 0 to 10 volts sawtooth and operate within the frequency of 100 to 1000 Hz. Also, 14 V p-p pulse waveform was required as an out-put. The circuit mainly consisted of hysteresis, which switched according to input from an integrator. The integrator was intern fed an adjusted output from the hysteresis. After analyzing systematically, the component values were determined and the circuit was implemented and tested part by part. The circuit operated as expected for the frequency range of 100 to 312 Hz, however, failed to behave properly for higher frequencies. It might be due to unaccounted capacitance effect; thus by adjusting the capacitor values of the integrator the circuit could be modified to meet the exact requirements.
