[VQ for a Gaussian Source] Using the LBG algorithm, design

[VQ for a Gaussian Source] Using the LBG algorithm, design two-dimensional vector quantizers of rates 0.5, l, 1.5, 2, 2.5, and 3 for a Gaussian source with mean 0 and variance 1. Plot the generated source output vectors and quantization points and determine the distortions.
