How do you find the phase of a complex number?

The angle or phase or argument of the complex number a + bj is the angle, measured in radians, from the point 1 + 0j to a + bj, with counterclockwise denoting positive angle. The angle of a complex number c = a + bj is denoted c: c = arctanb/a.

What is phase in complex numbers?

The phase (argument) of a complex number is the angle to the real axis of a line drawn from the point of origin (the intersection of the x-axis and the y-axis) to the point represented by the complex number.

How do you find the phase of a complex number in Matlab?

theta = angle( z ) returns the phase angle in the interval [-π,π] for each element of a complex array z . The angles in theta are such that z = abs(z). *exp(i*theta) .

How do you find the amplitude and phase of a complex number?

To find the Amplitude or Argument of a complex number let us assume that, a complex number z = x + iy where x > 0 and y > 0 are real, i = √-1 and x2 + y2 ≠ 0; for which the equations x = |z| cos θ and y = |z| sin θ are simultaneously satisfied then, the value of θ is called the Argument (Agr) of z or Amplitude (Amp) of ...
