Build the Circuit: Construct the function generator on a PCB or a breadboard, and connect the relevant components. Power the Circuit: Connect the +/-12V DC power supply. Select Waveform: Select the ...

The selection of the active function is digitally made, the main part of the function generator being common for all the computed functions. The circuit core, the current squarer circuit, will be ...

The actual circuit of the generator is built with three LM386 ICs. It produces two frequencies, selectable via double-pole double-throw (DPDT) switch S1 (Fig. 2).

The traditional analog function generator with its customary triple-threat ensemble of square, triangle, and sine waveform outputs is a familiar tool on electronics lab benches. It’s also a classical ...
