Regarding phase and frequency components in the signal



As I am not a signal processing student, I have limited understanding of the concepts.



The general formula for sine wave is


$$s(t)= A \sin(\omega t-p)$$


where $A$ is amplitude $\omega$ is frequency and $p$ is phase.




  1. Is there any possibility that the phase of the signal remains constant even if the frequency of the signal is changed?




  2. If we observe a real-time signal the signal can be a periodic sine wave signal but not smooth curve as it is accompanied by noise. In such cases how the phase of the signal is varied? Can the noise effect the phase of signal?

I have a question about matched filtering. Does the matched filter maximise the SNR at the moment of decision only? As far as I understand, ...
