1 kHz sine wave generator
This circuit generates a 1 kHz sine wave, adopting the inverted configuration of Wien bridge (C1-C2-R3 and R4). It has a variable output, low distortion and low output impedance, in order to obtain a good overload capacity. A small incandescent lamp ensures a long-term stable amplitude of output waveform.Notes:The lamp must be a low current (40-12V 50mA or 6V 50mA) in order to obtain good
