A full-wave bridge rectifier circuit with a 1-k ohm load operates from a 120-V (rms) 60-Hz household supply through a 10-to-1 step-down transformer having a single secondary winding. It uses four diodes, each of which can be modeled to have a 0.7-V drop for any current. What is the peak value of the rectified voltage across the load? For what fraction of a cycle does each diode conduct? What is the average voltage across the load? What is the average current through the load?
1- Describe the function of the program. DO NOT WRITE THE OPERATION OF EACH INSTRUCTION 2- Assuming that the branch instruction is executed (the branch is taken), comput the number of clock cycles required to execute the loop (DECA or BNE AGAIN)
A three phase load draws 100kW at a poer factor of 0.7 laggaing from a 220V line to line. In parallel with this load is a three phase capacitor bank which draws 60kVAR. Find the total line current and the resultant power factor.
For a chip area with area 2cm x 2cm in a 180nm logic technology, what is the approximate area of the same chip when ported to a 32nm logic technology.
send the pattern 0x99 to Memory Location VAR2 and call the delay function one more time. Repeat this operation eight times using a for loop. Assume that the bus clock frequency is 24MHz. Write the delay using inline assembly language.
Show that for wires of identical dimensions but made of different materials, such as copper and aluminum, the resistance is proportional to the resistivity of the material. the resistance of a certain copper wire is 1.5.
A 2.4KV, single-phase circuit suppllies a load of 250KW at a lagging power factor, and the load current is 160A. If it is necessary to improve the power factor, determine the following: (a)The uncorrected poer factor and reactive load.
Consider the following differential equation, where x(t) is the input and y(t) is the output: d/dt y(t)+5y(t)=2x(t) Suppose the input is x(t) = 4u(t) and the initial condition is y(0-) = 6 1. What is the impulse response for the system
A series-resonant RLC circuit has R = 80 (ohms), L=25mh, and C=10pF. A) Sketch and label the circuit. B) Find fo, the resonant frequency. C) At what frequency is impedance a minimum D) What is the magnitude of the impedance at this frequency
Digital Communications, Order the following modulation types in terms of spectral efficiency (best to worse) and explain
A purely inductive load of 10 ohms is connected to an ac source of 120 V (rms) through a half wave SCR circuit. a. If the SCR is triggered at 90 degrees, calculate the angle at the maximum instantaneous current.
A certain engine lathe can be purchased for $330,000 and depreciated over three years to a zero salvage value with the SL method. This machine will produce metal parts that will generate revenues of $220,000 (time zero dollars) per year.
