Final answer:
Locating and observing a symmetrical signal includes verifying symmetry, observing Doppler shifts without premature rounding, checking consistency of calculations, and ensuring frequency does not drift due to relative motion. Points in phase should be tested for same potential and set comparisons for in phase and out of phase points should be made to verify signal integrity.
Step-by-step explanation:
When locating observe a symmetrical signal, several aspects must be verified to ensure the signal integrity. Verifying the signal often involves looking at the following:
- Checking the symmetry of the signal, which for a round signal, should be consistent across all axes.
- Observing for any Doppler shifts that might indicate motion of the source relative to the observer or vice versa. These shifts should be calculated meticulously and compared with theoretical values without prematurely rounding off, as the effects are typically small.
- Ensuring that calculation steps are checked, and that the conclusion is reasonable, which includes verifying that the signs are correct, and the sketch or raytracing is consistent with the signal being observed.
Points in the signal phase should also be examined to test points with the same potential, identifying sets of points that are in phase and out of phase. In this context, in phase points would oscillate together, while out of phase points would be oscillating opposite to one another.
A practical verification step for circular signals includes checking the uniformity of the motion and its consistency with simple harmonic motion, which can be represented as a wave profile.
Finally, ensure the signal does not drift in frequency due to changing relative motion between the source and receiver. The consistency of the observed frequency (Fo) with the source frequency (fs), when adjusted for the relative speeds of the source and observer to the medium (usually air), will be an important consideration.
