94. The transfer function of a zero-order hold is
95. A random variable z, has a probability density function f(z), where f(z) = e-z 0 ≤ z ≤ ∞, the probability of 0 ≤ z ≤ 2 will be approximately
96. A signal m(t) band-limited to 3 kHz is sampled at a rate $$33\frac{1}{3}\% $$ higher than the Nyquist rate. The maximum acceptable error in the sample amplitude is 0.5% of the peak amplitude mp. The quantized samples are binary coded, then the minimum bandwidth of a channel required to transmit the encoded binary signal will be:
