Determine the Fourier Series Coefficients Ck for the output y(t) ofan LTI system with impulse response h(t)=e^(-t) u(t) to the inputx(t)=cos2t + sin3t
The air density is 1.23 kg/m^3. If the rolling frictional force is determined to be 47,500 N and the power required to sustain the current velocity is 4.681 MW, determine the approximate drag coefficient of the train
The receiver uses a 10.7 MHz IF. For cost, power, weight and size reasons, it is desirable to use a single clock oscillator that will provide the frequency reference for the synthesizer, as well as providing the clock for data.
if a circuit contains 3 automatic switches and we want that, with a probability of 95%, during a given time interval they are all working, what probability of failure per time interval can we admit for a single switch
Traffic lights are being converted from incandescent bulbs to LED arrays to save operating and maintenance costs. Typically each incandescent light uses three 100-W bulbs, one for each color R,Y,G,A competing LED array consists of 61 LEDs.
An NMOS operating in triode region with Vds=0.1V conducts 60μA forVgs=2V. The device conducts 160μA for Vgs=4V. Calculate Vt. IfKn'=25μA/V2 , what is the device W/L What current would flow for Vgs=3V and Vds=0.15V
A pacemaker is programmed to deliver pulses a certain times every minute for a patient with heart block. A 0.5µF capacitor controls the pulse discharges through a 2M resistor. One pulse is delivered every time the fully charged capacitor loses 50%
1.) (a) What is the difference between the sign-magnitude and 2's-complement systems of representing signed binary numbers. (b) What is the advantage of using the 2's-complement system to represent signed numbers.
X & Y are Gaussian random variables with E[X]=1, E[Y]=2, E[XY]=.1, VAR[X]=5 & VAR[Y]=10. Define the vector V=(matrix) 1 1;1 -1 matrix X;Y. Find the mean of E[V], covariance martix for V, use matrix notation
Write a matlab function to generate Gray coding matrix. The function has one input M where M=2^m and m is the number of bits per symbol. For example, if the function my_graycoding(4), the output should be
Assume that the basic inverter has (W/L)n = 0.5 um/0.25 um and (W/L)p = 2 um/0.25 um. What is the minimum area occupied by the circuit neglecting contact areas. Assume that the inputs A and B and their complements are available.
For a 12-bit linear PCM code with a resolution of 0.02 V, determine the voltage range that would be converted to the following PCM codes. (a) 1 0 0 0 0 0 0 0 0 0 0 1 (b) 0 0 0 0 0 0 0 0 0 0 0 0 (c) 1 1 0 ..
A Y-connected three phase supply has a balanced voltages of 110e^j0, 110e^(j2/3) and , 110e^(j4/3). The corresponding impedances on the Y-connected load are 30, 30+j40 and 40+j30 ohm.
