Build Your Own Sweeping Function Generator -
Part II
Power Supply, Output Amplifier, and V/I Converter Circuits
by Dennis Feucht
The FG506 sweeping function generator circuit design took place in the summer of 1973. Consequently, the level of integration is at most MSI (for the digital logic). A positive consequence is that no parts are mysteriously customized and undocumented. The board is two-layer through-hole, and the design could easily be simplified by being upgraded to use present-day ICs. (That might be a follow-on project.) The original, known-good design will be retained here, with comments given on upgrading. A '70s design also provides educational value for circuit-level understanding of analog electronics.
