This circuit uses an XR-2206 to provide sine,square,triangle,ramp and pulse output waveforms, which can be both amplitude and frequency modulated Electrical characteristics and functional circuits of the XR-2206 are shown in Figs 5-31B and C, respectively, The operating frequency is set by capacitor C between puts 5 and 6.The THD ADJ pot between pins 13 and 14 adjusts the waveform.R3 sets the amplitude（Fig.5-31D）The SYMMETRY ADJ pot between pins 15 and 16 is a fine waveform adjustment．Open S1 for triangle, close S1 for sine.The square output is at pin 11 .See Conditions in Fig. 5-31B
