If a random sequence has an autocorrelation function
Find the discrete-time, pure prediction Wiener filter.
That is, find the filter Such that when is input the output will be an MMSE estimate of
Determine and plot the PSD for the random sequence and the power transfer function,
Binary data is transmitted through an Additive White Gaussian Noise (AWGN) channel with SNR=3.5 dB and bandwidth B. Channel coding is used to ensure reliable communications. Then: i. What is the maximum bit rate that can be transmitted
Try to replicate the experiment carried out in Illustration 180. (f) On your own design a PLL as in Illustration 181 and try to set the control voltage for the VCO in such a way that the PLL works.
In practical implementations λ is small but often cannot be neglected. Use the linear model of the PLL and derive the transfer function
Four methods of injecting reactive power are available, involving the use of?
The sinusodial modulating wave m(t) = (Am)cos(2*pi*fm*t) is applied to a phase modulator with sensitivity kp. The unmodulated carrier wave has frequency fc and amplitude Ac. Determine the spectrum of the resulting phase-modulated wave
efficiency in a power transformer is 98.6 when loaded such that its core losses equal the copper losses. calculate
An amplifier represented with an input resistance of 10k ohm, an output resistance of 1k ohm, and the open circuit voltage gain of 1000 V/V is connected to a signal source of 10 mV peak amplitude with an internal resistance of 100k ohm.
Suppose X has a continuous uniform distribution over the interval [-1, 1]. (a) Determine the mean, variance, and standard deviation of X. (b) Determine the value for x such that P(fx
consider a 5 bit binary sequence. A one or zero is equally likely for each bit. Also each bit is statistically independent of the others. Let X be a random variable denoting the number of one in the sequence. Find the density and distribution of X
what load should be connected to terminals a-b of the circuits in Fig. 11.51 so that the maximum power is transferred to the load?
A combined-cycle, natural-gas, power plant has an efficiency of 52%. Natural gas has an energy density of 55,340 kJ/kg and about 77% of the fuel is carbon. a. What is the heat rate of this plant expressed as kJ/kWh and Btu/kWh
