An active network is described by the characteristic equation s^2+(3+6K1)s+6K2=0 It is required that the network be stable and that no component of its response decay more rapidly than K1e^-3t. Show that these conditions are satisfied if K2>0, |K1|<1/2, and K2>3K1. Crosshatch the area of permitted values of K1 and K2 in the K1-K2 plane.
1. express the following operatorsj j2 j3 a a2 a3 -a2 -a in rectangular form and sketch the operators in the complex
A 440 Vrms (line to line voltage) three phase induction motor runs at 1150 rpm driving a load requiring 15Nm of torque. The line current is 3.4 at a power factor of 80% lagging. Find the input power in Kw, The output power in Kw, and the efficiency..
If a single-loop circuit consists of an ideal 15-V dc source VS, a variable resistor R and the described Zener diode, find the range of values of R for which Zener diode remains in constant reverse breakdown with no danger of failure.
Design a circuit that can perform BCD addition on two decimal digits. You don't have to design any of the major components you may use (such as adders, comparators, etc.). Assume all those components are available.
Why Coaxial Cables are Highly Insulated? include also the Application of Coaxial Cables .
which electrical meters are self-powered from an internal source such as a battery, and which meters draw their power frm the circuit to which they are attached
Determine the cost of the energy delivered by this battery per kilowatt hour. Compare to the $0.12 per kilowatt hour for energy purchased from electric utilities in the United States.
A potentiometer is wired is wired to represent a rotational range of 0-180 degree. The potentiometer is supplied with a voltage of 15 VDC. What is the output voltage at 75 degree
Calculate the new mud developed by the coil and the peak flux and what is meant by mutual flux? by leakage flux?
Consider a discrete-time linear time-invariant system with impulse response h[n]. If the input x[n] is a periodic sequence with period N (i.e., if x[n]=x[n+N]), show that the output y[n] is also periodic sequence with period N.
he armature at the other end of thecommutator is tapped and connected to balanced 3-Phase voltages, sothat a rotating field is produced, The speed of this rotating fieldis 3000 r.p.m. (1) clockwise and (2) anticlockwise,.Find thefrequency of the b..
Given the following difference equation with the input-output relationship of a certain initially relaxed system (all initialconditions are zero), y(n) - 0.7 y(n-1) + 0.1y(n-2) = x(n) + x(n-1)
