Diode bridge and FET form constant－current source charging c1,to make voltage across c1 change at linear rate as required for triangle output across c1． Frequenεy can be adjusted from 500 Hz to above 20 kHz with constant output amρlitude, by means of R1 Short -term stabilityis better than1 partin l0.000 Since the same R and C are used to generate both sections of the waveform,ρositive and negative slopes are identical,Diodesare HP 5082-2810．－G.
