The transfer function of the first order system is:
H1=1/ST+1
The transfer function of the second order system is:
H2=T^2/S^2+2δs+T^2
T=99
Add those two as a closed loop and then convert the continuous closed loop system into a discrete system using z-transform?
a certian voltage is +10V for 20ms and -10 V for the succeding 20msand continues osciallating back and forth between these two valuesat 20ms intervals. The voltage is present across a 50 ohmresistor. over any 40ms interval
Design a multiplexer which has four input lines, two controllines, and one output line and a demultiplexer which has one input line, two control lines, and four output lines using truth tables and k-maps.
With a 500hp shunt wound DC motor, at 1800rpm, 500Vdc, FLA is 800Adc, Ra is 0.025 and Rf is 400. What would Va need to be if you wanted the motor to operate at 1000rpm at rated torque. Keeping the field current constant.

Consider a (Nt,Nr) =(4,4) MIMO channel. For the input of the channel x = [x1,x2,x3,x4] assume that each xi is drawn from a BPSK constellation with energy P. Also assume that the channel noise variance is σ2 =1
A voltage of 100 VDC is applied across a resistor, and the temperature of the resistor is measured. Which of the voltage waveforms shown in the figure, when applied across the resistor, would produce that same temperature - What is the value of t..
One rod is made from lead and another from quartz. The rods are heated and experience the same change in temperature. The change in length of each rod is the same. If the initial length of the lead rod is 0.13 m, what is the initial length of the ..
Two bar magnets are placed in a straight line with their morth poles 5 cm apart. (a) what is the force of repulsion if M1=25.1*10^-5 Wb and M2=6.28*10^-5 Wb. (b) what is the field intensity at the M2 north pole as a result of the M1 north pole.
A hot-air balloon is rising upward with a constant speed of 3.86 m/s. When the balloon is 9.27 m above the ground, the balloonist accidentally drops a compass over the side of the balloon. How much time elapses before the compass hits the ground
