In a single instrument, sine, triangular, and rectangular waveforms are usually generated using R-C charge/discharge networks followed by appropriate filters. Alternatively and certainly more fashionably these days, such signals can be synthesized by a microprocessor. The function generator described here follows a conceptually different approach and matching circuitry.
