Uses CD4011 IC operating from 1 5-V AC Iine as at left.NAND gates of IC are connected as at right, with G1serving as integrator with variable delay time, G2-G3as Schmitt trigger, and G4as triangle to sine-wave converter.Sine-wave approximation, depending on transf er function of G4,is calibrated by R3and R4.Values of R1and R2 may be varied between 0.01 and 10 megohms and C between 100 pF and 2.2 μF to obtain desired sawtooth and pulse waveforms at desired frequency determined by setting of R5.-J.
