Function Generator 12 Steps with Pictures Circuit Diagram 1) Using IC 4049. Using only one low-cost CMOS IC 4049 and a handful of separate modules, it is easy to create a robust function generator that will provide a range of three waveforms around and beyond the audio spectrum.. The purpose of the article was to create a basic, cost-effective, open source frequency generator that is easy to construct and used by all hobbyists and lab professionals. In other words, if we want a function generator circuit with adjustable amplitude and an output buffer, we need to make a few changes to the previous circuit, which yields the circuit shown below. This circuit incorporates an amplifier circuit, IC2 TL082.
A function generator can generate different kinds of signals like sine wave, square wave or even a triangular wave at a particular frequency set by the user. The design explained in this ible uses AD9833 which can ideally generate frequencies up to 12.5 MHz as per the datasheet. The Basics of the Circuit. As mentioned above, a few simple physical input and output components control the signal that the Arduino generates. For that purpose, this project utilized two 20K Ohm potentiometers and two 10K resistors to build a voltage divider that will reduce the voltage from five volts to 3.3 V. Note that this may not be
