How to compute phase of the signal?

In summary, the conversation discusses the possibility of computing the phases of three signals from a given phase spectrum or equation of the main signal. It is mentioned that this can only be done if the functional form of the 3 signals is known, otherwise it cannot be done uniquely. The conversation also mentions not using an equation that is the sum of 3 signal functions.

Suppose you are given a phase
spectrum or (/and) equation of the (main) signal only and you are said that the given (main) signal is
formed of 3 other signals.
Is it possible to compute phases of these three signals from the
equation or (/ and) phase
spectrum of the (main) signal?
Also,what information is containedin the phases of these signals?

Note : You can take any equation
of your choice.but just not take
equation of sum of 3 signal
functions. at least mix 2 signal
functions together

I'm not sure what you are asking - are the 3 signals of known functional form? If not, then this cannot be done uniquely.

By the way, the last part of your post makes this sound like a homework question. Is it?

Related to How to compute phase of the signal?

1. What is the phase of a signal?

The phase of a signal is a measure of the position of a waveform in its cycle, relative to a reference point. It is often represented in degrees or radians and can range from 0 to 360 degrees or 0 to 2π radians.

2. How is the phase of a signal computed?

The phase of a signal can be computed using mathematical techniques such as Fourier analysis, which breaks down a signal into its constituent frequencies and their corresponding amplitudes and phases. Other techniques such as the Hilbert transform and complex demodulation can also be used to compute the phase of a signal.

3. What is the importance of computing the phase of a signal?

Computing the phase of a signal is important for many applications in science and engineering, such as signal processing, communications, and control systems. It can provide information about the timing and synchronization of signals and can also be used to extract useful information from a signal.

4. Can the phase of a signal change over time?

Yes, the phase of a signal can change over time, especially in dynamic systems where the signal is affected by external factors. This change in phase can be measured and analyzed to understand the behavior of the system.

5. What are some common challenges in computing the phase of a signal?

Some common challenges in computing the phase of a signal include noise, interference, and non-stationary signals. These factors can affect the accuracy and reliability of the phase computation and may require advanced techniques for signal processing and data analysis.
