The sampling rate and step-size Δ of the delta modulator are 20,000 samples per second and 0.1 V, respectively. To prevent slope overload, the maximum amplitude of the sinusoidal signal (in Volts) is A uniformly distributed random signal x[n] with mean m x = 2 and variance $$\sigma _{\text{x}}^2$$ = 3, is passed through a 3-point moving-average filter having an impulse response $$\left\{ {{\text{h}}\left[ {\text{n}} \right] = \frac{1}{3},\,\frac{1}{3},\,\frac{1}{3}} \right\}.$$ What will be the mean and variance of output? A source produces three symbols A, B and C with probabilities P(A) = $$\frac{1}{2}$$, P(B) = $$\frac{1}{4}$$ and P(C) = $$\frac{1}{4}$$. The source entropy is Which of the processor is a good match for applications such as video games?
