This circuit uses the positive temperature coefficient of lamp filaments in a modem adaptation of a classic oscillator circuit. A variable Wien bridge provides frequency tuning form 20 Hz to 20 kHz. Figure 5-1B shows the oscillator waveforms, while oscillator distortion versus is plotted in Fig. 5-1C.
