Revise the night-light circuit of Figure 1.3 to include a switch that selects between activating the light when it is dark and activating the light during night-time hours. Assume there is a timer that produces a 1 output at night.
Calculate A - B for the pair of numbers, 1101011, 0101010 assuming a two's complement number system and that the numbers are stored in one byte of memory. The numbers are in un-complemented form.
b)what is the total power in the signal the power in the DC portion of the signal and the power in the time-varying portion of the signal c) write the equation for and sketch the power spectral desity of the random signal
Determine the value of the output voltage due to the voltage source only (Vol), and due to the current source only (V02).
A thermal generating station has an installed capacity of 15 MW and supplies a daily load of 10W for 12 hrs and 5MW for remaining 12 hrs.- what is the plant capacity factor and reverse capacity on the plant?
A unipolar 16 bit ADC measures 0-10 volts full scale. a) What is the minimum resolvable voltage b) What is the percent quantization error c) What is the percent quantization error if a 1 volt max signal is input
Often when developing a new wireless digital communication protocol it is useful to develop a simulator to evaluate the various methods available for communication of the data.
Regulated DC Power Supply design problem. The students must choose the values of the following parameters for the design:VOut = 6.0 V or 10.0 V or 12.0 V RL = ?? ? and R1 = ?? ?
Two Loads are in parallel with a 2000 Volt sinusoidal source.Load 1 draws 40 Amps at 0.5 lagging power factor. Load 2 draws 15Amps at 0.8 leading power factor. (a) Make a table showing each load and its complex power
Find the estimator g(Y) of X, in terms of F, that minimizes the mean square error MSB: = E[(X - g{Y))2],
A 3kw, 120V, 2400 rpm shunt motor has an armature resistance of 0.4 ohms and a shunt field resistance of 160 ohms. The motor operates at full load. The no load current is 2A. If an external resistance of 2.5 ohms is insertions in the armature circ..
single phase motor draws 20A from a 200V, 50Hz supply with a lagging power factor of 0.8. Calculate the value of the capacitance needed to bring the current in phase with the voltage.
2 coils are 80% magnetically coupled for a magnetic system. Suppose that coil 1 is excited by AC voltage V1=200 v with current I1=1 A, all in rms values at 60Hz, while coil 2 is open and receives an induced voltage V2 = 50 v in rms.
