Let x(n) be the input signal to a discrete-time filter withimpulse response hi(n) and let yi(n) be the corresponding output.x(n) = {1,4,2,3,5,3,3,4,5,7,6,9}h1(n) = {1,1}h2(n) = {1,2,1}h3(n) = {1/2 ,1/2}h4(n) = {1/4, 1/2, 1/4}These sequences are written such that the first value islocated at instant n=0.(a) Plot x(n) and y1(n).(b) Show that y2(n), y3(n) andy4(n) can be obtained from y1(n)
A transistor current source (also known as current ''sink'') was built with a 2N3904. The Ic was measured for different values of a load resistance. It was noticed that Ic was pretty much constant for the first 1900 ohms values
A 50 ohm source is connected to a 50 ohm receiver using 30 ft of RG58U coaxial cable. If the source output is 100 MHz and -30dBm, determine the voltage at the receiver in mV and dBuV [6.05 mV , 75.6 dBuV
A circular disk having a radius of 4 ft and weighing 40lb has a small weight of 20lb attached to it at a distance of 2ft from its center. If the disk is in the vertical plane and set in rotation about an axis through
Determine the phase margin of the uncompensated and compensated system from the Nichols chart. (The graph on the left is uncompensated, the one on the right is compensated. What is the DC gain of the compensated closed loop system.
Design a common collector circuit using a npn silicon transistor having Beta=90 with Vcc=20 V The desired Q-point is Vce=14V and Ie=2mA
A balanced star load of 8+j6 O per phase is connected to three-phase, 230 V supply. Find the line current, power factor, power, reactive VA and total VA.
Calculate the %age second harmonic distortion present in the amplifier's output for a sinusoidal input of 10 mV r.m.s.
4 resistors are connected in electrical parallel. R1=2 OHM, R2= 4 OHM, R3= 6 OHM, R4= 8 OHM. if this parallel resistor combination is placed across an ideal current source = 3A.
A labor intensive process has a fixed cost of $338,000 and a variable cost of $143 per unit. A capital intensive (automated) process for the same product has a fixed cost of $1,244,000 and a variable cost of $92.50 per unit.
Simplify the following circuit. Line A goes into an INVERTER, then into a NAND Gate, then into an OR Gate, then travels into another NOR Gate.
A power company supplies 75 kW to an industrial load. The load draws 120 Arms from the transmission line. If the load voltage is 440 Vrms and the load power factor is 0.8 lagging, find the losses in the transmission line.
a total charge Q is uniformly distributed around a ring shape conductorwith radius a.a charge q is located at a distance x from the center of the ring ....the force exerted on a charge is given by F=(qQx)/(4πε(x2+a2)3/2)
