Gives simultaneous sine, square, and triangle outputs with low distortion (1%), high linearity (0.1%), 0.05 Hz to1 MHz frequency range, and duty cycle of 2% to 98%. Intersil 8038 waveform generator feeds buffer amplifier using 2N3709 transistor, switched to desired output waveform. Timing capacitors C1-C8, determining frequency decades of signal generator, start with 500,μF for 0.05 Hz to 0.5 Hz and decrease in submultiples of 10 to 500 pF for 50 kHz to 500 kHz. C8 is 250 pF for final range of 100 kHz to 1 MHz.-H. P.Fisher, Precision Waveform Generator, 73 Magazine, Dec. 1973, p 41-43.
