A speech signal has a total duration of 10 s. A speech signal has a total duration of 10 s. It is sampled at the rate of 8 kHz and then encoded. The signal-to-(quantization) noise ratio is required to be 40 dB. Calculate minimum storage capacity needed to accommodate this digitized speech signal. Is this […]

A sinusoidal signal of frequency A?0 = 104/2π Hz is sampled A sinusoidal signal of frequency A?0 = 104/2p Hz is sampled at the rate of 8 kHz and then applied to a sample-and-hold circuit to produce a flat-topped PAM signal s (t) with pulse duration T = 500Âľs (a) Compute the waveform of the […]

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. Is […]
