Audio Phase-Shift Oscillator with Amplitude Stabilization - Here is a phase-shift audio oscillator with excellent distortion characteristics thanks to "softened" diode limiting provided by the 1N914 and resistor divider and degenerated gain provided by the 68 ohm emitter resistor. For minimum distortion….(added 05/05/05)

Phase Shifter - ASCII format (electronic circuit added 7/03)

Phase Shifter (engal) - The classic, swishy sound of the 70s and 80s is coming back. Be ready with this interesting effect. Provides 0 to 180 degrees of phase shift, with a variable sweep control. Works for keyboards and guitar. (Circuit design added 11/06)

Phase Shifter Yields Slope Polarity Detection - 03/14/96 EDN-Design Ideas....The circuit in Figure 1 uses a phase shifter to provide an output signal that represents the polarity of the slope of an analog signal. You can use it for square-wave shaping of sinusoidal signals or for highpass filtering. V1839 and V1841 can range from 9 to 18V and -9 to -18V, respectively. The unity-gain isolation amplifier IC1.... [Design Idea by Paul Kemp, NASA, Houston, TX]

Potentiometer Controls Phase Shift - 02/15/96 EDN-Design Ideas....You can use dual, quad, or hex potentiometers to put all phase-shift sections under control of a microprocessor, as in Figure 2. The DS1806 hex digital …. EDN is migrating links. This link is not verified. Search the "title" + "EDN" for new link.

Scheme extends DDS phase shift resolution - 08/05/99 EDN-Design Ideas....Direct-digital-synthesis (DDS]devices find wide use in instrumentation and communications applications. Rather than using a baseband converter to modulate data in a communications system, you can use a DDS device. Such a device has onboard phase registers that accommodate.... EDN is migrating links.
