Title: Function Generator Purpose: The purpose of this experiment is to construct a function generator capable of taking a DC input and producing different outputs. The three desired outputs are a sinusoidal wave, a square wave, and a triangle wave. The function generator should also include a DC offset adjustment as well as amplitude control for the output waveform. Procedure: Components to be used: DC power supply ( +15 Volts), 3 1N4148 diodes, one LED, 4 741 op-amps, 3 0.01 micro-farad capacitors, 2 1 …

…a DC input into a sine wave. By taking this sine wave, and putting it into the input of a Schmitt trigger the, the sine wave is transformed into a square wave. The last stage, the integrator emits a triangle wave, when the output from the Schmitt trigger is applied to its input. Through the use of various potentiometers throughout the circuit, it allows for the adjustment of the frequency, amplitude, and the DC offset.
