What is a complex sinusoid?

1) The real part of a complex sinusoid is a cosine wave and the imag- inary part is a sine wave. 2) A complex sinusoid x(t) = Ae. jΩt+φ can be visualized in the complex. plane as a vector of length A that is rotating at a rate of Ω radians per second and has angle φ relative to the real axis at time t = 0.

How do you make a complex sine wave in MATLAB?

sine = dsp. SineWave creates a sine wave object that generates a real-valued sinusoid with an amplitude of 1, a frequency of 100 Hz, and a phase offset of 0. By default, the sine wave object generates only one sample. sine = dsp.

How to generate complex signal in MATLAB?

y = imag(complexSignal); plot(x, y, 'bo-', 'LineWidth', 2);

How do you plot a complex plot in MATLAB?

Plot One Complex Input

With complex inputs, plot(z) is equivalent to plot(real(z),imag(z)) , where real(z) is the real part of z and imag(z) is the imaginary part of z . Define z as a vector of eigenvalues of a random matrix. z = eig(randn(20)); Plot the imaginary part of z versus the real part of z .
