What is the time constant for a circuit composed of a real inductor (L=.4H and R=50ohms) and a 150 ohm resistor connected in series?
Plot the steady state torque-speed characteristic for Va = 100V, 60V, and 30V. Calculate the armature voltage to be applied in the steady state at the speed of 1500 rpm when the motor torque load require is 3 Nm.
A 480-V, 60Hz, 500-hp 0.85-PF-leading eight-pole delta-connected synchronous motor has a synchronous reactance of 0.6 ohms and neglible armature resistance. Ignore its friction, windage and core losses for the purposes of this problem.
Capacitors c1= 8.50μF andc2=3.50μF are charged as a parallel combination across a 36-V battery. Calculate the initial voltage across, and initial chargeon each capacitor. a) Calculate the resulting charge on each capacitor
(a) Find the matched-filter frequency response function H(f) for a perfectly rectangular (video) pulse of duration τ, andamplitude A. (Assume the pulse extends in time from -π/2 to+π/2). (b) Sketch (roughly) its magnitude abs {H(f)} for positive fr..
convert the decimal +46 and +29 to binary, using the signed-2's-compliment representation and enough digits to accommodate the numbers. Then Perform the binary equivalentof (+29)+(-49), (-29)+(+49), (-29)+(-49).
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.
Design a circuit that will display the decimal numbers that are less than 60 by using two 7-segment displays. The number 60 should be displayed as 00. Use the least amount of IC's as possible.
A series connected DC motor has R_F + R_A = 11.5 ohm and draws 1 A of current from a DC voltage source with V_T = 18 V while running at 1000 rpm. What is the speed and developed torque when drawing 0.75 A of current
an amplifier operating from + - 3V supplies provides a 2.2-V peak sine wave across a 100 ohm load when provided with a 0.2-V peak input from which 1.0 mA peak is drawn. The average current in each supply is measured to be 20 mA.
a.) Determine where the given poles are mapped into the z-plane.b.) How would you determine if these poles are mapped inside, on, or outside the unit circle in the z-plane. Explain.
An Ideal Low Pass Filter: The impulse response of an ideal low-pass filter is h(t) = sin(t)/t (or the sinc signal). (a) Given that the impulse response is the response of the system to an input x(t) = f(t)with zero initial conditions
