The key to good opposite sideband suppression with single sideband transmitters using the phasing method rests on the audio phase shifter. Simple audio phase shifters as designed by Dome and Norgaard were able to achieve 40db opposite sideband suppression over the range of 275 to 2750Hz. Beyond this audio base band, sideband suppression rapidly deteriorates and …
Audio Effects - Phase Shifter - Anadigm

The 4-stage audio effect uses 2.5 CABs of an AN221E04 FPAA. This document also discusses design variations which offer different design and software options to the user, and provides some bench characterizations of the design. These FPAA designs are included as AnadigmDesigner®2 design files as part of this Starter Kit.

Re: Audio phase shift circuit design wanted. So, the phase shift (of 180 deg) will need to be adjustable for any frequency over the audible spectrum. Then you simply want an inverting opamp stage. But as others pointed out, you can't cancel a …
Frequency Independent Phase Shifter - Circuit Cellar
https://circuitcellar.com/research-design-hub/frequency-independent-phase-shifter/
As mentioned earlier, traditional phase shifters are designed using an all pass filter, with a phase shift varying from 0 degrees to 180 degrees for a given frequency. A slight variation of frequency would lead to a drastic change in the phase.

- In audio phase shifting, a sound engineer can produce a strange guitar or another instrumental effect by overlaying a second phase-shifted signal on the original. When these signals are 180 degrees out of phase— one wave starts at half the time period of the first wave from the same source, causing a positive wave to meet the second negative wave— the sound …

A simple phase shift circuit can be implemented using an allpass filter. Figure 1 As the signal frequency varies from DC to infinity, the phase shift will vary from 0 to +180 degrees. You can also see that by varying R1, the phase shift at a given frequency will vary likewise. If the position of R1 and C1 are reversed, as in Figure 2, the transfer function becomes Application Note 184

• The phase shift value deviates linearly from the intended value as the frequency of the signal deviates in either direction from the center (nominal) frequency. • Switched-line Phase Shifters generally are used for 180° and 90° phase shifts. When path L2 is a half wavelength (λ/2) longer than path L1, switching from path L1

The capacitors must be large enough to maintain stability but not introduce too much phase shift and amplitude attenuation at audio frequency. With a 1.2-ηF capacitor, the fp = 308 kHz, the phase shift at 20 kHz is 7°, and the amplitude attenuation is 0.03 dB; this is …
