The highest frequency in a telemetry signal representing the rudder position of a ship is 2 Hz. What is the shortest time for the rudder to change to a distinctly new position? Hint: refer to Fig. 9.3a, which shows that a signal change from a min to a max takes place in a time of a half-cosine
Resistance=0.09ohm/km Inductance=1.4mH/km Capacitance=8.8x10-3 uF/km. Calculate the sending-end power if the receiving-end voltage is 132kV and the receiving-end power is S2=100+j60 MVA. Assume a pi-equivalent circuit.
If a system has a unit-impulse-response of h(t) = 100t * e^(-20t) u(t) , where u(t) is the standard unit step function, then determine the transfer function H(f) for the system. What type of filter is this system (high-pass, low-pass, band-pass, ..
How should three capacitors and two batteries be connected so that the capacitors will store the maximum possible energy
Design a MEALY MACHINE sequence detector state machine that outputs a 1 whenever the sequence 01 or 10 is detected in its input stream: 1. Draw state diagram 2. Perform state assignment
What is the applied voltage? What is the resulting frequency of the waveform? What is the corresponding rotor shaft speed? Verify that the simple motor rotates, and note how much voltage is needed to turn the motor.
Identify, design, simulate, and test a circuit. In this weeks lab you will identify, design, simulate and test a given circuit.
The phasor voltage Vab in the circuit is 480 /0° V (rms) when no external load is connected to terminals a,b. When a load having an impedance of 100 j0 Ω is connected across a,b, the value of Vab is 252.9822 /-18.3449° V (rms).
The underground cable is now supplying 8 kV to an 800 kVA, 0.9 PF lagging single-phase load. What is the sending end voltage and current of this transmission line?
The current density in a cylindrical conductor of radius R = 43.1 cm, varies as J(r) = J0r/R (in the region from zero to R), where J0 = 0.417 C/m2. a) Find the magnitude of the magnetic field at r = 21.55 cm.
Assume there is no electric field in this problem. Hint: angular acceleration is u2 /r where u is the velocity of the particle and r is the radius of the circular path. the frequency of the particles path is u/r.
Consider a virtual memory system that can address a total of 232 bytes. You have unlimited hard drive space, but are limited to only 8 MB of semiconductor (physical) memory. Assume that virtual and physical pages are each 4 KB in size.
