A star-bus hybrid topology consists of a main three branch star toplogy with each branch connecting three stations in a bus topology. This toplogy is changed to a new bus-ring hybrid topology with main five station bus topology and one of the stations on this bus topology being part of a five station ring topology. In this new hybrid topology, only one station is common to the bus and the ring topologies. Compare the number of transmission paths required in these two hybrid topologies.
e) What is the value of C such that the energy stored in the capacitor equals the energy stored in the inductor f) How much energy is stored in the 3.9?F capacitor Use the formula for the energy. g) What is the power dissipated in the resistors
An AM broadcast receiver's pre-selector has a total effective Q of 90 to a received signal at 1180 kHz and uses an IF of 455 kHz. Calculate the image frequency and its dB of suppression.
8. What is Mac OS X's present day file system A) Macintosh Filing System (MFS) B) Hierarchical Filing System (HFS) C) Hierarchical Filing System Extended (HFS+) D) Extended File System (EXT) Th..
A 1.0 dc voltage source is connected across a 10 ohm resistor. What is the current through the resistor if (a) the voltage source is ideal (b) the voltage source has internal resistance 0.1 ohm (c) internal resistance 1.0 ohm
The rotor of a 3phase, 5kw, 400v, 50Hz, slip ring indution motor is wound for 6 poles while its stator is wound for 4 poles. The approx average no load steady state speed when this motor is connected to 400v, 50Hz what is the supply
draw the sympol and truth table of the gate that corresponds to the action of the logic gate.
We represent this by a non-overlapping sequence detector. In other words, asa soon as you detect the sequence, you will need to get another complete sequence to unlock. Therefore, you need to carefully choose to which state you will need to go.
Using 4 PSK or 2 PSK with the same total power as a reference, calculate the Eb/No versus Pe waterfall plot and compare the asymptotic coding gain of the coder/encoder.
Two resistances R1 and R2 are connected in series. We know that R1=60 ohms and that the voltage across R2 is three times the value of the voltage across R1. Determine the value of R2.
An analog signal ranging between 0 and 1 V must be quantized. The midrange quantization errors must be no greater than 0.1V. How many quantization bits must be used to satisfy this requirement
Suppose we had connected at the input to channel 0 a circuit of the type that attenuates all frequencies above 50 Hz at a rate of 6 dB/octave. What will we then see in the output when we apply 4960 Hz at the input
The temperature of steam at the inlets of both turbines is 500°C, and the enthalpy of steam is 3185 kJ/kg at the exit of the high-pressure turbine, and 2247 kJ/kg at the exit of the low-pressure turbine. Disregarding the pump work, determine the w..
