Consider a uniform quantizer characterized by the input—output r Consider a uniform quantizer characterized by the input—output relation illustrated Figure a. Assume that a Gaussian-distributed random variable with zero mean and unit variance is applied to this quantizer input. (a) What is the probability that the amplitude of the input lies outside the range -4 […]
Consider a test signal m (t) defined by a hyperbolic tangent Consider a test signal m (t) defined by a hyperbolic tangent function: m (t) = A tanh (βt), where A and β are constants. Determine the minimum step size ∆ for delta modulation of this signal, which is required to avoid slope overload.
