For the first two code lines I prefer, Fs = 10; L = 10; t = (0: L - 1) / Fs; x = 0.3 * cos(2 * pi * t); where Fs is sampling frequency, L number of samples and t shows the time. Note that x is sinusoidal with frequency of Fx = 1 Hz or we can say that it's periodic with Tx = 1 sec. For 8-bit quantization we have 256 levels. Since L / Fs = [10 sample] / [10 sample/sec] = 1 sec is equal to Tx (a whole period of x) we can work with positive samples. Mx = max(abs(x)); mx is defined because in order to use floor we need to scale the x. Q256 = mx*(1/128)*floor(128*(x/mx)); mx shows the maximum value for x so x / mx will take values over [-1 1] and 128*x/mx over [-128 128] will cover all 256 levels.

So we will quantize it with floor and scale it back ( mx*1/128). Download Church Management Software on this page. E256 = (1/L)*sum(abs(x-q256)) e256 simply shows the mean error over 10 samples. Note that if L / Fs. Cei 82 25 Terza Edizione Pdf Files.
