Learn how to use the function generator at Sears think [box], Case Western Reserve University’s open-access innovation center and makerspace.

The result is a cheap function generator you can build with a Pi Pico and a handful of resistors, which will probably cost you the grand total of $12.

A frequency-tunable function generator with rectangular and triangular pulses and control of equivalent capacitances is shown.

The calculation is based on four function generator equations as shown in Figure 6. Figure 6 Creating the ultrasound rangefinder waveform using sample-based calculations. Source: Arthur Pini The ...

If you have a modern function generator on your bench it is quite likely to contain a direct-digital synthesis circuit that creates arbitrary waveforms using a microprocessor controlled DAC. If ...
