A signal can be modeled as a lowpass stationary process X (t), whose probability density function (PDF) at any time t0 is shown in Figure P-7.16.
The bandwidth of this process is 5 kHz, and we desire to transmit it using a PCM system.
1. If sampling is done at the Nyquist rate and a uniform quantizer with 32 levels is employed, what is the resulting SQNR? What is the resulting bit rate?
2. If the available bandwidth of the channel is 40 kHz, what is the highest achiev· able SQNR?
3. If, instead of sampling at the Nyquist rate, we require a guard band of at leas1 2 kHz and the bandwidth of the channel is 40 kHz, what is the highest achievablt SQNR?
Construct two branches of a hyperbola when its transverse axis is 50 mm long and foci are 70 mm apart. Locate its directory and determine the eccentricity.
A 2-conductor cable 1 km long is required to supply a constant current of 200 A throughout the year.- Calculate the most economical conductor size.
ManchesterEncodingFSM the clock (Clk_H) will need to run at a speed that is twice as fast as the clock that defines the boundaries of the RawSerialIn_H serial data bit cell this will allow the FSM to resolve or discriminate the middle of each raw ..
A collimated light beam from a helium-neon laser at 632.8 nm wavelength impinges on a dielectric film of refractive index of 2.0 at an angle of 75 degrees to normal, with a polarization at 45 degrees to the plane of incidence.
Computer the following assuming each number is a two's complement number and indicate the inputs and final result in decimal. Also, indicate if the number overflows. a. 01 + 1011 b. 11 + 01010111 c. 1101 + 110 d. 01 + 10 e. 111 + 111111
A transmission line with no loss, with Z0= 60 ohms, is operated at 60MHz. The velocity on the line is c. The line is soldered to a ground connection at z=0. Find the input impedance into this line at z= -1.25 meters
Design an experiment to compare analytically estimated wear rates with the experimental wear rates.
Determine formulas in closed form for the marginal probability distribution function of X for all x, and sketch a graph of this function over the range -1 ≤ x ≤ 2.
120V, 60 Hz source is connected to a distribution line whose resistance, and inductive reactance is 0.001Ohm, j0.002 Ohm, respectively. Single phase, 100HP, 120V, 0.85 pf. motor and 100Kw, 120V heater are connected in parallel.
The windings of high-current electromagnets are often made of copper pipe. The current flows in the walls of the pipe, and the cooling water flows in the interior of the pipe. Suppose the copper pipe has an outside diameter of 1.2 cm and inside di..
In free space, a solid metal sphere ofradius 3 cm, centered at the origin, supports a surface chargedensity of 4.421 mC/m2. Surrounding it is a concentric hollow metalsphere of radius 5 cm with a surface charge density of -1.273mC/m2.
A ring conductor of radius 1 m is located on the xy-plane, centered at (0, 0, 0), and carries a current of 1 A in the counter-clockwise direction. A line conductor parallel to the y-axis and passing through (1, 0, 1) carries an unknown current I.
