Function Generator

Using an Intersil ICL8038, this function generator generates frequencies from 1 Hz to over 80 kHz. Rl is the fine freque
Function Generator - schematic

ncy control and SI is the coarse frequency control range switch. S2 selects square-, triangle-, or sine-wave output. U2 is a buffer amplifier and R5 sets output level. R2 is adjusted for a symmetrical triangle wave. R3 and R4 are adjusted for minimum sine-wave distortion. Power supply is ± 12 V at less than 100 mA.
