A, B, Bin, D and Bout are respectively the minuend, the subtrahend, the BORROW-IN, the DIFFERENCE output and the BORROW-OUT in the case of a full subtractor. Determine the bit status of D and Bout for the following values of A, B and Bin:
Explain how the basic strategy of control is employed in a room air conditioning system. What is the controlled variable? What is the manipulated variable? Is the system self-regulating?
What are the advantages of a current controlled device over a voltage controlled device , and advantages of 4-20mA loop over a closed loop voltage
It is connected to a transformer whose primary contains 2000 turns and is connected to 110-V household outlet. How many turns should there be in the secondary? What is the current in the primary? How many Watts does the bell require from the tr..
How many time slots does the GSM TDMA have? Based on North American TDMA (IS 54), and comparing it to AMPS, what is the bandwidth utilization improvement with this type of TDMA? Give at least three advantages of using CDMA as a cellular access t..
A particular inverting amplifier with nominal gain of -100 V/V uses an imperfect op amp in conjunction with 100-k ohm and 10-M ohm resistors. The output voltage is found to be +9.31 V when measured with the input open and +9.09 V with the input gro..
Calculate β for two transistors for which α=0.99 and 0.98. For collector currents of 10 mA, find the base current of each transistor.
A capacitance C=35 uF is in parallel with a certain element. Identify the element, given that the voltage and total current are v=150sin3000t(V) and i of tau=16.5sin3000t+72.4 degrees (A)
Design an 8-bit ripple-carry adder and draw its schematic. Useblock symbols for two circuits, a half adder and a full adder.Label all inputs, outputs, and connections. Use a half adder forthe LSB, and full adders for the remaining 7 bits.
A three-phase 60-Hz line has flat horizontal spacing. The corductors have an outside diameter of 3.28cm with 12 m between capacitive. Determine the capacitive reactance to neutral in ohm-meters and the capacitive reactance of the line in ohms if i..
Compare your result with the conductivity of copper (see Appendix 4). You will notice a difference between these conductivities by several orders of magnitude. Why? (Compare only the same units!)
A lossless transmission line with the electrical length of l = 0.3 lamda and the characteristics impedance of Z0 = 75 is terminated with a complex load ZL = 30 -j20 calculate the reflection coeficient at the load, the SWR on the line
