How do you find the phase angle of a graph? As final output I want to have a number from 0 to 511 to indicate this phase shift. In your case, there is no phase shift or 'c'. For example, sin(x) and-sin(-x) produce the same output. Surely the 2 antennas receives reflection from a single target with a phase shift. The Period goes from one peak to the next (or from any point to the next matching point): The Amplitude is the height from the center line to the peak (or to the trough). Expanding what's inside the sin function: v(t) = sin (100πt - 0.2π). Asked 18th Apr, 2018 ; Hisham Hashim; I'm a new user to python. Looking at this function, you see that it is already in standard form, so you can go straight to step 2 and label your values. Phase shift simply assumes that one cycle is 360° (or 2π radians). Or we can measure the height from highest to lowest points and divide that by 2. One tenth of this is 36°, or 0.2π radians. If it's not a leap year the year is 365 days long and June 21st is the 172nd day of the year. How to find the phase difference between two signals by using python? Mentor. Disadvantages.
