Consider a discrete-time, analog sourcewith memory,i.e.,U1, U2, . . .are dependent rv's.Assume that each Uk is uniformly distributed between 0 and 1 but that U2n=U2n-1foreach n=1. Assume that{U2n}8are independent. n=1
(a) Find the one-bit (M= 2) scalar quantizer that minimizes the mean-squared error.
(b) Find the mean-squared error for the quantizer that you have found in (a).
(c) Find the one-bit-per-symbol (M= 4) two-dimensional vector quantizer that minimizes the MSE.
(d) Plot the two-dimensional regions and representation points for both your scalar quantizer in part (a) and your vector quantizer in part (c).
Using Mesh Technology, find in the circuit of figure 1.- Using Krichhoff's laws, calculate the current delivered by the battery shown in figure 2.
Drift velocity the actual (physical) velocity of electrons along the wire. Transmission velocity the rate at which information can be transmitted electronically using conducing wires. How is it possible that the transmission velocity is so much faste..

Using Quartus II, or an equivalent VHDL entry program, develop the text file and simulation for the 74LS194A universal, bi-directional shift register. Attach the .vhd and simulation files.
Write and test a program for the EASy68k to input a string from the keyboard and output a reversed string to the screen. Use a subroutine to perform the string reversal operation.
Draw the waveform that results on output RB7. If the waveform is repeating, then say so and draw at least two cycles. Also, clearly indicate logic '0' and logic `1' on your waveforms.
An AC motor with impedance Z = 4.2 + j3.6 Ω is supplied by a 220 V, 60 Hz source. Determine the reactive power delivered to the load.
R- 1k ohm; L=1nH for the circuit represented in Fig. 8.1, and with the knowledge that i(0) = -3mA: a) Write an expression for i(t) valid for all t>=0 b) Compute i(t) at t=0, t=1ps, 2ps, and 5ps
Model a slab of Drude material in 2D with dispersive permittivity only per wavelength and make the slab 100 grid cells thick. Launch a sinusoidal wave at the slab with a wavelength of 1 cm ( f = 30 GHz) and observe the wave phase behavior in the ..
