An ultrasound image analog signal needs to be converted to a digital bit stream. The bandwidth of the signal is from 500 kHz to 2.0MHz, and the necessary resolution is 12 bits. determine the required sampling rate and the data rate (bits/second of the resulting bit stream
In a balanced three-phase wye-wye system, the load impedance is 10 +j1 Ohms. The source has phase sequence abc and the line voltage Vab = 220 Vrms /30°. The load voltage is VAN = 120 Vrms /0°.
Write a MATLAB program to compute the capacity of an AWGNC with a given bandwidth and for equally spaced values of between and including and (in dB).
The factorial of a nonnegative integer n is written n! (pronounced "n factorial") and is defined as follows: n!= n(n-1)(n-2)(n-3)....1 (for values of n greater than or equal to 1) and n!= 1 (for n=0) for example 5! = 5x4x3x2x1,
In a power supply, a 150 microfarad capacitor was connected in parallel with a 200 kOhm resistor. The capacitor was maintained at a charge level of 350 volts DC. After power was removed for ten seconds, someone god a shock from touching the termin..
1- If the diameter of a spherical water droplet is 100.0 µm, how much energy is required to increase the diameter of the water droplet by 3.0 µm The surface tension of water is 1.0 x 10-3 J/m2. 2- A metal crystallizes in a face-centered cubic lat..
A parallel-resonant RLC circuit has R = 75 I, L=50mh, and C=45pF. A) Sketch and label the circuit. B) Find fo, the resonant frequency. C) At what frequency is impedance a maximum D) What is the magnitude of the impedance at this frequency
A signal x(t) can be represented as x(t)=xe(t)+xo(t) where xe(t)=(1/2){x(t)+x(-t)} is the even part, and xo(t)=(1/2){x(t)-x(-t)} is the odd part of the signal. Let x(t) be an energy signal with an energy of 20 Joules. Suppose the even part of x(t) is..
A "ferrite" having a relative permeability of 50 H / m, that operates with flux densities sufficiently small, may be considered a single material. If the magnetic flux density in the material is B = 0.05 T, H and M. halle How to compare the values
In one type of computer keyboard, each key holds a small metal plate that serves as one plate of a parallel-plate, air-filled capacitor. When the key is depressed, the plate separation decreases and the capacitance increases.
Do either or both of the reasons you gave in part (a) above also apply to a point to point voice link using frequency modulation? c. Which parameter of an FM transmission determines whether it is wideband or narrow band?
Write an asm HCS12 program to flash LEDs on a dragon+ board three times when SW5 is pressed with a 5 kHz frequency, and 50% duty cycle clock signal. Generate a clock signal with 5 kHz frequency, and 50% duty cycle.
(a) The ideal delay system. y[n] = x[n-nd] (b) The accumulator system. y[n] = sum (xk) , k from -inf to n (c) Forward difference system. y[n] = x[n + 1]- x[n] (d) Backward difference system. y[n] = x[n]- x[n - 1]
