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.

Use the method of constrained least squares. Display the phase response of the filter. Design the same filter using fircls1. Keep in mind that fircls1 uses linear units to measure the ripple and attenuation. Design a lowpass equiripple filter with normalized passband frequency 0. Design an elliptic lowpass IIR filter with normalized passband frequency 0. Transfer function coefficients, specified as vectors. Express the transfer function in terms of b and a as. Number of evaluation points, specified as a positive integer scalar no less than 2. When n is absent, it defaults to For best results, set n to a value greater than the filter order. Second-order section coefficients, specified as a matrix.

The size of the output Q is always the same as the size of the input P. Support Answers Matlab phase.

Find the phase angle of the spiral from the x - and y -coordinates using the atan2 function. Note that this plot has discontinuities. Use unwrap to eliminate the discontinuities. Shift the phase angle of a frequency response.
