What is the phase of complex number?

Every nonzero complex number can be expressed in terms of its magnitude and angle. This angle is sometimes called the phase or argument of the complex number. Although formulas for the angle of a complex number are a bit complicated, the angle has some properties that are simple to describe.

How do you change the phase of a complex number?

Amplify a signal and phase shift it by multiplying by a complex...

1. Change the real signal to a complex signal. ( ...
2. Multiply it by the phasor Aeiθ
3. So the calculation is Aeiθ(eω1t+eω2t)
4. Where A=10 is an amplitude change and θ=0.5π/180 is the phase change caused by the equipment.

What is the general for of a complex number?

A complex number is a number of the form a + bi, where a and b are real numbers, and i is an indeterminate satisfying i² = −1. For example, 2 + 3i is a complex number.
