Figure 12.83 shows a 3:8 decoder [Lyon87]. How does the logical effort of each input compare to an ordinary decoder made of 3-input NORs? Does the decoder have any performance drawbacks?
The p.d. across and the current in a circuit are represented by (100 + j200) V and (10 + j5) A respectively. Calculate the active power and the reactive power.
Write Boolean equations for a BCD decoder, that is, a decoder that has a BCD code word as input and that has outputs y0 through y9. Draw a circuit that uses AND and OR gates and inverters to implement the decoder.
A six pole, 40 kW, 400 V d.c. motor draws 110 A from the supply. The shunt field resistance is 200 Ohm and the armature resistance is 0.5 Ohm. The armature is wave wound with 600 conductors operates at a speed of 1200 rev/min when supplying full l..
An exponential signal, x(t) = 4e-2t , is sampled at a frequency of 10 Hz, beginning at time t = 0. - Express the sampled sequence, x[n], up to the fifth term.
Assume that a given transformer is 100% efficient; that is, the power being supplied by the primary side is transported without loss to the secondary side. (Transformers are not 100% efficient. One can detect this by the heat that they radiate.)
Three parallel three-phase loads are supplied from a 207.85-V rms, 60-Hz three-phase supply. The loads are as follows: Load 1: A 15 hp motor operating at full load, 93.25 percent efficiency, 0.6 lagging power factor.
Let D = 4xy ax +(2x2+2z2) ay + 4yz az nC/m2 and evaluate surface integrals to find the total charge enclosed in the rectangular parallel piped 0
In a power supply, a 150 microfarad capacitor was connected in parallel with a 200 kOhm resistor. The capacitor was maintained at a charge level of 350 volts DC. After power was removed for ten seconds, someone god a shock from touching the termin..
In the "far field" region, show that the electric field intensity of a linear electric quadrupole decays much faster in space than 1/R3 for the electric field intensity produced by an electric dipole and 1/R2 for an electric monopole.
A first order lowpass filter is operating in sinusoidal steady state conditions at a frequency of 2 kHz. It is determined that the positive peak of the output is delayed by 0.1 ms compared with the positive peak of the input.
Design a 7.5-V zener regulator circuit using a 7.5-V zener specified at 12mA. The zener has an incremental resistance r(z) = 30 ohms and a knee current of 0.5mA. The regulator operates from a 10-V supply and has a 1.2k-ohm load.
Briefly, the speed is adjusted unless the probability that the mean thickness lies within ±2% of the sample mean exceeds 0.99. A typical set of measurements (in mm) is as follows:
