Figure 2 shows that oscilloscopes of two sinusoidal voltages, their phase shift is adjusted to 1.0 degrees. With the cursors function a time difference can be read off from 2.8 µs. For 1 kHz means: correspond to 1 kHz = 1ms 360 degree. Then …

phase in the undesired direction. In the phase -shift method of dis-tortion measurement, the input sig-nal is reversed 180 degrees with re-spect to the output signal, and the two signals mixed after they are ad-justed to equal amplitudes. If there is no distortion, the two signals be-ing equal in amplitude and opposite in phase (See Figure 2A) will can

1) What would be an audible measured phase shift at different frequencies? 2) since the phase shift of Class D in the old thread was actually a time delay, wouldn’t that be of no consequence unless you had multiple amps in your setup with different time delays? " The thought you cannot think controls you more than thoughts you speak aloud.

and the phase then varies from -180 to 0 degrees. The phase shift this circuit realizes at any given frequency can be found by where w is the frequencies in rad/s, or 2*pi*f, when f is in Hertz. As a practical matter, most circuits of this type can comfortably cover a phase range of about 120 degrees with real op amps and components.
Phase shift measurement - Pico Technology

To find the phase shift between two signals (Ch A and B) I: a) Add a cycle time measurement to Ch A (or B). b) Use cursors to measure the time delay between signal A and B. c) Calculate the phase shift from the information above. Is it possible to implement a measurement into PicoScope 6 that calculates the phase shift (in deg) between Ch A and B.

This choice of references defines the two most common phase measurements: device input/output phase, and interchannel phase. Phase shift varies with frequency, and it is not uncommon to make phase measurements at several frequencies or to plot the phase response of a frequency sweep. Phase is expressed in degrees.

Since the top and bottom heads of the drum are usually moving in directly opposing motion (when the top drum head is hit, it moves inward, causing the bottom head to move outward), the two mics will record signals that are directly out of phase.

A delay of 0.5ms would shift it by 90° and a delay of 1.5ms would shift it by 270°. A 2ms delay would obviously shift our 500Hz wave by a full cycle and this wave would look identical to the original. This part should be relatively easy to understand. If you can’t grasp this concept yet, go back over it until you do.
