Frequency Modulation is the process of varying the frequency of the carrier signal linearly with the message signal. Phase Modulation is the process of varying the phase of the carrier signal linearly with the message signal.

In a sinusoidal wave. the angle giving the phase of the wave (i.e., its shift relative to the wave with ) is called the phase angle. It represents the fraction of the period that y lags or leads the function . Phase. © 1996-2007 Eric W.

Phase is the angle difference measured from the peak of a vibration signal backward in time to the reference trigger point. At this point, the phase is zero degrees. The following figure shows a phase of 90 degrees and the relationship between a vibration signal and reference signal.

Oscillations and Waves Solution: Express a displacement at t = 0 via initial phase: x(0) = A cos φ. The initial phase is φ = arcos [x(0) /A] and further φ = arcos(– / 2). Two angles correspond to these phases φ1 = (5π/6) and φ2 = (7π/6). To find for a certain phase we have to use the condition (0)<0.

Initial phase angle is defined as phase under initial conditions(t=0). Denoted by φ. It determines the angle between the starting position and the original. So the initial phase angle determines from where the observation starts.

Initial Phase means the first phase of the Facility, which shall include the facilities described in the Initial Scope of Work. The Initial Phase shall be designed and constructed so that it will be an integral part of the Final Scope of Work. Sample 2.

a(t) = -ω2A cos(ωt + φ) = -ω2x. The quantity φ is called the phase constant. It is determined by the initial conditions of the motion. If at t = 0 the object has its maximum displacement in the positive x-direction, then φ = 0, if it has its maximum displacement in the negative x-direction, then φ = π.
