The minimum step-size required for a Delta-Modulator operating at 32 K samples/sec to track the signal (here u(t) is the unit-step function)

x(t) = 125t(u(t) - u (t - 1) + (250 - 125t) (u (t - 1) - u (t - 2 )) so that slope - overload is avoided, would be

$${2^{ - 10}}$$

$${2^{ - 8}}$$

$${2^{ - 6}}$$

$${2^{ - 4}}$$

The following question refer to wide sense stationary stochastic process:

The parameters of the system obtained in Q. 12 would be

first order R-L low pass filter would have $$R = 4\Omega \,L = 1\,H$$

first order R-C high pass filter would have $$R = 4\Omega \,C = 0.25F$$

tuned L-C filter would have $$L = 4H\,\,C = 4F.$$

series R-L-C low pass filter would have $$R = 1\Omega ,\,L = 4H,\,\,C = 4F.$$

The following question refer to wide sense stationary stochastic process:

It is desired to generate a stochastic process (as voltage process) with power spectral density

$$$S\left( \omega \right) = {{16} \over {16 + {\omega ^2}}}$$$

By driving a Linear-Time-Invariant system by zero mean white noise (as voltage process) with power spectral density being constant equal to 1. The system which can perform the desired task could be

first order lowpass R-L filter

first order highpass R-c filter

tuned L-C filter

series R-L-C filter
