a. Show by a suitable sketch that the triangular spectrum of Figure 4.8(a) satisfies Nyquist's pulse shaping criterion.
b. Find the pulse shape function corresponding to this spectrum.
A radiant wall heater black body radiator is a silica cylinder 1.0m long and radius 0.5mm. It is rated at 1KW. If the room temperature is 300K, estimate the working temperature of the heater, stating any assumptions.
A 100 W bulb takes 0.833A and a 200 W bulb takes 1.67 A from a 120V source. If the two bulb were connected across a 240 V source, what current in amperes will flow through the bulbs?
Filament 1 is on the left, filament 2 is in the middle, and filament 3 is on the right. Filaments 1 and 2 have currents of 1 A in the ba z direction, and filament 3 has a current of 2 A in the ba z direction.
It costs $30,000 to retrofit the gasoline pumps at a certain filling station so the pumps can dispense E85 fuel. if the station makes a profit of $0.08 per gallon from selling E85 and sells an average of 20,000 gallons of E85 per month
Gaussian random variable W is known to have P[W>4] = 1/2. Based on this information, (a) sketch its possible PDF. (b) Now also assume that Var[W] is very small. Refine your sketch in the first part taking into account this new information.
The binary-coded-decimal (BCD) format uses 4 bits to represent 10 decimal digits. For example, 259 in base 10 is repesented as "010 0101 101" in BCD format. A BCD incrementor adds 1 to a number in BCD format.
Find the maximum torque on an orbiting charged particle if the charge is 1.60E-19C, the circular path has a radius of 0.5E-10m, the angular velocity is 4E16 RAD/S, and B=0.4E-3T.
Ninety-five percent of the acetone vapor in an 85 vol% air stream is to be absorbed by countercurrent contact with pure water in a valve-tray column with an expected overall tray efficiency of 50%. Calculate: (a) The minimum value of L'/ V', the rati..
Use as few 2x2 MUXes as possible to design the following circuit. Your circuit outputs Z, which is the square root of the input, X if and only if X is a power of two, otherwise, the output Z=0. Assume the following range for X: 0
Usually, transformers are designed to operate with peak flux densities just below saturation of the core material. Why would we not want to design them to operate far below the saturation point? Far above the saturation point? Assume that the vol..
Consider the common-source amplier shown in Figure. The NMOS transistor has KP = 50 A/V2, L = 5 m, W = 500 m, Vto = 1 V, and rd = ∞. Determine the values of IDQ, VDSQ, and gm.
Calculate the overall heat transfer coefficient (U) for the assumed tube diameter, finshape and material. Use correlations to estimate hot-and cold-side convectioncoefficients, conduction resistance, contact resistance (if any), and fouling resist..
