Help Matlab phase Help Center. If P is a matrix, unwrap operates columnwise. If P is a multidimensional array, unwrap operates on the first dimension whose size is larger than 1.

Help Center Help Center. Gain margins are expressed in dB on the plot. Solid vertical lines mark the gain margin and phase margin. The dashed vertical lines indicate the locations of Wcp , the frequency where the phase margin is measured, and Wcg , the frequency where the gain margin is measured. The plot title includes the magnitude and location of the gain and phase margin. Gm and Pm of a system indicate the relative stability of the closed-loop system formed by applying unit negative feedback to sys , as shown in the following figure. The frequency Wcp at which the magnitude is 1.

Phase-Coded Waveforms When to Use Phase-Coded Waveforms Situations in which you might use a phase-coded waveform instead of another type of waveform include: When a rectangular pulse cannot provide both of these characteristics: Short enough pulse for good range resolution Enough energy in the signal to detect the reflected echo at the receiver. The first jump is 3. The output phi is single precision. Output Arguments collapse all Gm — Gain margin scalar array. Search MathWorks. Off-Canvas Navigation Menu Toggle. Since Ra Frequency range to consider in stability analysis, specified as a two-element vector containing the lower and upper limits of the range. You can customize certain characteristics of the waveform, including:. Express the transfer function in terms of b and a as.
