03/07/2002 EDN - Design Ideas /
Digital potentiometers are versatile
devices; you can use them in many filtering
and waveform-generation applications. This
Design Idea describes an oscillator in which
setting the resistance of two digital
potentiometers independently programs the
oscillation amplitude and frequency.

The Wien bridge oscillator is reborn:
06/13/2002 EDN - Design Ideas / In 1940, William
Hewlett and David Packard launched a product from a
garage. The product was a Wien-bridge oscillator. It
consisted of a single-pole highpass filter in series
with a single-pole lowpass filter. To keep the gain
constant, the circuit used an incandescent pilot
light to provide AGC (automatic gain control) Twin T Audio Sine Wave Oscillator:
