# Calculate phase difference between two signals python

I'm a new user to python. For part of my project, I have 2 signals which more or less are in the form of "sine wave" with the same frequency and amplitude. I plot each one of them separately and its looks good. But, when I wanted to average them, I found some strange effect on each other and I supposed that there is a Phase difference between them.. The phase difference, in degrees, can be determined using the equation: Φ = t d /t p × 360 = 10 ns/100 ns × 360º = 36º. Where: t d is the delay between waveforms and t p is the. 600/150 = 4 so you get 4 steps [or 90 degrees] phase resolution. You want better resolution, while staying with an FPGA? OK, but this gets a bit funky... First, you need 2 circuits, "lead" and "lag". We also need to label our signals "T" [Test] and "R" [Reference]. The "lead" is: T AND (NOT R). "Lag" is: R AND (NOT T). and plot the phase difference: plt.plot(x, phase_diff) plt.xlabel('phase difference') When the phase difference between y and y1 is 0, meaning both phase1 and phase2 = 0. The result looks reasonable. Similar to the case where phase difference is 180 degree, phase1 and phase 2 = 1. However, when the phase differnce is 90 degrees, meaning phase1. The phase difference between a signal on the tag and the two antennas is -180° to 180° range. Ultra-wideband, or UWB, is a short-range RF technology for wireless communication that can be leveraged to detect the location of people, devices, and assets with unrivaled precision.

Aug 13, 2018 · The phase difference, in degrees, can be determined using the equation: Φ = t d /t p × 360 = 10 ns/100 ns × 360º = 36º Where: t d is the delay between waveforms and t p is the period of the waveforms.

Aug 05, 2012 · As the purple signal's phase shifts the difference signal's amplitude increases. The error signal is zero when both signals are in phase (at t = 5). Here both signals start out at the same phase, and the difference signal is only caused by the difference in amplitude. So you'll have an offset if both signals don't have the same amplitude.. Figure-1: 2. Use v1 to interrupt the MCU over INT0-pin and start TC0 to count 16 MHz clock of MCU. 3. Use v2 to Stop TC0. 4. Read counts of TC0 which is proportional to.
